Don't be afraid to print out the details and study them.Also, if you want to try your hand at writing your own papers, always make sure that you understand the guidelines. Always make sure that you know exactly what is expected of you and that you understand what you are supposed to do. This will save you from ending up with a bad grade on a test, or having to redo a portion of your work. Do not skip over this part of the process.In addition, if you are in a class where there is only one person grading the paper, or you are assigned to a book report assignment, make sure that you are in your seat. If you are late, you will end up getting an F on the assignment. There is nothing worse than having to try and re-do something you failed on because you were late.Another thing to remember is that don't go out of your way to avoid your lecturer. Some lecturers find that students are very rude and disruptive when trying to talk to them about a paper. If you notice that you are having problems getting your lecturer to understand your paper, keep trying to explain it and do your best to be polite.Overall, most students who use their algebra tutor online will find that it will help them learn faster. There are many courses that can be found online which can help you understand the concepts of your algebra better. All you need to do is take the time to find the one that is best for you and learn from it.If you do not seem to be learning as fast as you would like, then try looking at the problem areas and try to find out why you are not doing well on the material. Some students might be learning the concepts correctly, but they are not being taught the right way.

It was the moment in which English ascendancy in the high seas became a real possibility.And, of course, it was the time in which kings and queens were the most fascinating, the most dastardly, and the most dramatic â€" with beguiling private lives , presiding over massive cultural production, and making England the country that it would later become.Yet, are all these things we think we know about the House of Tudor â€" and Tudor England in general â€" actually true? Is there anything left in this period in the history of England â€" from Henry VII to Elizabeth I â€" that is still surprising?Of course there is! And in this article, we’re going to look at some of the things you might not have known about the period â€" from the illegitimacy of the dynasty to the forgotten other king.Let’s take a look at some of the more surprising things about the Tudors.

A Lancastrian, his House of Lancaster defeated Richard III of the House of York at the Battle of Bosworth Field to end the thirty-year long Wars of the Roses. Whilst Henry VII, after his coronation, very successfully cemented his position as a unifying force in English politics â€" marrying the Yorkist Elizabeth of York to end the War of the Roses â€" his position was actually really very vulnerable.His claim to be king was through his descendance from Edward III’s fourth son, John of Gaunt, and his mistress. Henry’s great-grandfather was therefore illegitimate â€" and Henry’s claim came through his mother’s side. This was something not very well thought of during these times.Henry was only the Lancastrian candidate to be king because all of those with a better claim had been killed during the war. And so, in many ways, he should never have been king in the first place.Find out more about the Tudor monarchs!The Scots and Welsh Might Not be Very Happy if You Called the Tudor Monarchs ‘British’When talking about the Tudors these days, the phrase ‘British history’ is always at risk of slipping out. Yet, at this point in time â€" the sixteenth century â€" there wasn’t really any such thing as ‘Britain’ at all.Scotland was a different country entirely â€" and one with which the English were continually at war â€" whilst Wales was hardly a defined thing at all either. It wasn’t until 1536 that Henry VIII’s Act of Union made Wales a part of the territory of the Tudor monarchs.Before that, Wales was administrated by the Principality of Wales and by the Marcher Lordships, which protected the border of England and lawless Wales.Although They were Actually WelshThe Tudors themselves were actually Welsh, with Henry Tudor descending from the Tudors, a family of the Welsh nobility.Henry VII’s grandfather was a certain Owen Tudor, who Anglicised his Welsh name, Owain ap Maredudd ap Tudur. He was the second husband of Catherine of Valois â€" whose first husband was Henry V â€" and his own father participated in the Glyndwr Rising, the last major demonstration of Welsh independence from England in the ear ly fifteenth century.Discover more about who the Tudors were!King Henry VIII Didn’t Break from Rome Just because of Anne BoleynIn our great national fantasy, the primary reason that Henry VIII instigated his massive political upheaval in the 1530s was due to his love â€" or lust â€" for Anne Boleyn.However, this is only really half of the story â€" if that.The promise of a marriage to Anne Boleyn â€" after a divorce from Catherine of Aragon â€" may well have sweetened the deal, yet this wonderful entwinement of personal life and statecraft is mainly romance.Rather, the main reasons for Henry’s break from Rome were a bit more political. He’d spent all of the country’s cash on a load of useless wars throughout the first half of his reign â€" and the promise of plenty more from ecclesiastical property was really quite appealing.There was massive dissatisfaction with the Catholic church across Europe, and this could be used as a way to facilitate his plans.

Sure, George III went mad and Charles I was executed. But no-one was used so cynically â€" and suffered such a fate so young â€" as Lady Jane Grey.Held up by Edward VI and his advisor, John Dudley, Duke of Northumberland, as the heir to the throne in 1553, Lady Jane didn’t find much support when she was proclaimed queen that year. Rather, the few supporters she did have soon turned against her.And, when Mary I was proclaimed queen nine days later, Lady Jane was imprisoned and, ultimately, executed. She died at the age of sixteen or seventeen.Despite this tragedy, she may well have been the first woman to have been queen of England. This depends who you are talking to, because some people say that this was Empress Matilda back in the twelfth century. Others say that Lady Jane was never actually queen at all, but that the first queen of England was actually her successor, Mary I.Mary I Doesn’t Really Deserve the Name ‘Bloody Mary’Mary Tudor, or Mary I, really has a bad reputation. Such a bad reputation, in fact, that she’s more commonly known by her nickname, ‘Bloody Mary’, than by any other name.These days, historians are realising that this isn’t exactly fair. Sure, Mary I did indeed have a few people killed during her reign â€" but not near as many as her fellow Tudors. In fact, the 283 people that she had burned at the stake seems rather dignified and restrained in comparison to the rest of her family.Henry VIII is said to have executed over seventy thousand people, for example â€" which we’d surely all agree seems a little excessive. Elizabeth, whilst admittedly ruling for much longer than Mary, had six hundred people executed too.We Should Really Stop Being So Mean about Mary TudorShe wasn’t really that bloody, Bloody Mary. In fact, she had a bit of a tough life, honestly.From puberty onwards, she was regularly ill â€" more so than many in her time and position. She was believed to have had something known as ‘strangulation of the womb’ â€" which ultimately caused her to believe herself pregnant even when she was not.Maybe she wasn’t such a bad queen after all, as many of the things that Elizabeth has been so praised for â€" financial stability and naval expansion â€" were actually Mary’s ideas. Elizabeth I (1533-1603) Queen of England and Ireland from 1558, last Tudor monarch. Version of the Armada portrait attributed to George Gower c1588. (Photo by: Photo 12/UIG via Getty Images)Queen Elizabeth I of England Wasn’t as Universally Popular as We Might Now BelieveAnd just as Mary has developed a bit of a bad rep, maybe Elizabeth wasn’t such a great queen as we like to imagine.Under her rule, England underwent a whole serious of rebellions and attempted coups. There was the Northern Rising of 1569, the famous attempt to put Mary, Queen of Scots on the throne; the Ridolfi Plot of 1571, which saw an Italian banker try to arrange a Spanish invasion of England; and the 1583 Throckmorton Plot, again revolving around Mary, Queen of Scots, that aimed to murder the Queen.Find out more about life under the Tudors!The English Didn’t Really Defeat the Spanish Armada in 1588One of the funniest things about courses on the Tudors in secondary schools is that they all end in 1588, the year of the Spanish Armada, which was defeated by the English by good luck and some bad British weather.In fact, in 1589, Elizabeth ordered a ‘counter-Armada’, led by Francis Drake and John Norreys. This, in turn, failed dramatically, and actually ushered in another long period of Spanish dominance in the seas.In light of this, the episode of the Spanish Armada doesn’t seem like much of a victory at all.There’s Another Monarch in Tudor History that We All ForgetStrangely enough, we usually remember five, or six, Tudor monarchs: Henry VII, Henry VIII, Edward VI, Lady Jane Grey (maybe), Mary I, and Elizabeth I.However, there was a further monarch during this period that people generally forget.This was Philip II of Spain, the husband of Mary I and holder of the title ‘King of England’. In diplomatic despatches, in parliament, and even on English coins, Philip was recognised as King of England â€" and it was high treason to deny his authority.However, he couldn’t read a w ord of English. In fact, all state matters had to be published in Latin or Spanish so that he could understand them!

How to Help Your Elementary School Student Cope with Test Anxiety

How to Help Your Elementary School Student Cope with Test Anxiety Many students experience test anxiety, especially on standardized exams or assessments that affect their promotion to the next grade. As a result, its important for students to develop test-taking skills since they're used throughout primary and secondary school, as well as into college and beyond. If your elementary school student has test anxiety, here are four ways to help him or her cope: 1. Know the assessment(s) First, find out what exam your student is anxious about. There are many different kinds: unit tests in a specific subject, mid-year assessments, end-of-year exams, and more. Some tests take all week with a special testing schedule while others may be a few hours or may fit within a single class period. Is the format multiple-choice or short answer/essay? Will students use computers or test by hand? Youll want to know the purpose of the exam and its format and depending on that information, youll be able to discuss with your child an appropriate attitude toward it and how much significance it should have in his or her life. These tips to help you analyze practice test resultsmay help ease some test anxiety. 2. Communicate with your students teacher Your childs teacher can tell you more about the test, and youll be able to discuss with him or her how students are preparing for it at school, as well as anything helpful that you can do with your child at home. Ask the teacher for any resources or tactics that might be helpful for the specific exam, as these can help to lower your elementary school students text anxiety. He or she may refer you to someone within the school who has more or different information, such as the principal. In any case, communication with your students teacher should help you better understand the test, as well as what your child is doing in school to get ready for it. 3. Practice test-taking skills at home Even though your home is a different environment than your students school, discuss and practice test-taking skills there. Depending on the age of your child, you may want to talk about filling in bubbles, carefully reading directions, eliminating answers, skipping and returning to questions, and double-checking your responses. You may also want to talk about time management throughout an exam so that your student doesnt feel rushed. When you speak with your childs teacher about the test, ensure that what you are doing at home works and is helpful for the exam in order to best lower test anxiety. You may also want to consider a test prep tutorwho can help reassure your child. 4. Encourage your child to eat and sleep well during exam week On test days, make sure your child eats and sleeps well. Balanced meals and a good nights sleep will help to ensure that he or she has the necessary brain energy to do well during the day. If the exam spans several days, teachers often give little or no homework during this time. In that case, plan after-school relaxation time for your student. A schedule of healthy eating, sleeping, and winding down should help your elementary school student cope with test anxiety. These tips may help your child mentally prepare for test day. Even though many assessments are high-stakes, dont forget to emphasize learning for learnings sake. Celebrate your child for what he or she has learned and done well in throughout the year. Even when not directly linked to test-taking, these moments of success may help your studentfeel better about school and about taking important assessments.

Senior Year College Resolutions

Senior Year College Resolutions Youve finally made it to senior year. Youre older, you no longer have to carry a map of campus, and youre starting to get wise to those myths about the last year of college. As a senior, you have college all figured out. However, it is never too late to make a few improvements or to prepare for the next stagethe real world. Let your year of lasts be your year of bests with these four senior year college resolutions. 1. Finish college stronger than you started Senioritis can drain your motivation and shift your focus, but you know better than to let it take control of your last year of college. Instead, take all the wisdom and experience of the last three years and use it for good. You have had three years to experiment, make mistakes, and hopefully learn from them. You know which subjects you excel in, where you do your best studying, and how much work you have to put in to get the grade. Put this knowledge to use to have your best semester ever. To finish your college experience on a strong note, take time to make a list of habits that have worked for you in your first three years. Did you take advantage of your professors office hours? Did you pursue honors projects and extra credit opportunities? Likewise, take a moment to reflect on which classes were the most difficult for you. What mistakes did you make? You now know better, and recognizing the mistakes can ensure you dont make them again. 2. Gain real-world experience in your prospective industry Senior year is a great time to step off campus and gain some real-world skills in a professional setting. Consider finding an internship in your area of study. Many colleges and departments provide help in the form of an internship coordinator, who may assist students to find potential opportunities and make connections. Get to know this person well during your senior year. You can also personally reach out to local businesses and inquire about any internship opportunities. As an intern, you can gain the experience and communication skills needed to succeed in your field. Having an internship can also give you an edge over other candidates when it comes to applying for jobs in the future. If an internship isnt in the picture for you, consider job shadowing. A job shadowing opportunity allows you to observe the day-to-day duties of a person in your prospective industry. Reach out to a professional in the field to see if you can shadow him or her throughout the week, or even meet with him or her over coffee one day to discuss the nature of his or her job. Plus, in the real world, who you know is important. Finding connections while you are still in college can give you a step up when it comes to searching for jobs. Volunteering is another great way to gain experiencewhile helping others. Find a cause that you care about, then reflect on how your skill set can contribute to that organization. Are you a journalism major? Help the organization with their social media needs. Studying business and economics? Any organization would appreciate assistance with fundraising. Volunteering for a cause gives you experience and connections that can help you in the future. 3. Fully utilize campus resources There are tons of resources available to students on campus. Often, these resources are either free or rolled into your total tuition cost. Once you are on your own, you may need to front the cost of comparable resources, so use them while they are still free and readily available! For example, your college gym can help you reach your fitness goals and expand your fitness knowledgesomething youd pay a pretty penny for in the real world. Likewise, mental health services, a student health center, or entertainment on campus are all opportunities to take advantage of as well. In addition, your career services office can provide assistance and tools to help you succeed in your job or graduate program search. Through career services, you can make connections in your dream field, create your first resume, and plan for post graduation life. Also, be sure to schedule a mock interviewyour career counselor can provide feedback on your performance to help you master an interview. These resources, like a professional resume consultant or career coach, would cost hundreds of dollars in the real world. 4. Give back to your university Make this year the year that you make a difference on campus. After everything your college has given you, its important that you give back to your college as well. Four years may seem like a short time to leave a legacy, but there are several ways that you can ensure you change your college for the good before you leave. You could implement a new program in your student organization, or raise money for a scholarship fund for students from your hometown. Maybe you mentor a freshman, helping him or her through the first year of college, or you assist a professor with a research study. These are all ways to have an indelible effect on your college for years to come. With these senior year college resolutions, you are making a commitment to make the most of your last year of college. Your senior year is a time to gain experience and prepare for your future in the workforceutilizing campus resources, seeking internship opportunities, and reflecting on your best academic habits can ensure you have the tools needed for future success.

Ratio Simplifier- Maths Online TutoringTutorpace

Ratio Simplifier- Maths Online TutoringTutorpace Ratio is the quantitative comparison between quantitates or numbers. Ratio is a very commonly used operation in mathematics. Ratio helps in solving questions related to comparisons, proportions and many more. The symbol of ratio is :. For example, a / b can be written as a : b. Here a / b is fraction form and a:b is the ratio form. The simplification of ratio is writing the given ratio in the most simplified from possible. Example 1: Are the ratios equivalent? 50 students taking Math class and 75 students taking English class. 30 students taking Math class and 45 students taking English class. Solution: Here for the given question the ratio is between the number of students taking Math class and the number of students taking English class. The first ratio given is Number of students Math : English = 50 : 75 Simplifying the ratio gives 2 : 3. The second ratio given is Number of students Math : English = 30 : 45 Simplifying the ratio gives 2 : 3. Therefor the two ratios are equivalent. Example 2: Simplify the given ratio 48 : 96 Solution: Here the given ratio is 48 : 96. Here the numbers 48 and 96 are divisible by 2. Simplifying the ratio gives 24 : 48.

Simplifying Complex Fractions Online Tutoring Maths Help

Simplifying Complex Fractions Online Tutoring Maths Help Simplifying is a method to reduce or simplify a given expression to simpler form. Complex numbers are non-real numbers which are undefined on the number line. A complex number is of the general form a + bi, where a is the real part of the complex number and b is the imaginary part of the complex number. Here i is the representation of the imaginary numbers and has a condition of i2 = -1. A complex number written in the p/q form is called as complex fractions. Example 1: Simplify the complex number fraction 5 / (3 + i)? Solution: Given is the complex number fraction 5/(3 + i) Here the complex fraction has 5 in the numerator and (3 + i) in the denominator. To simplify multiply the numerator and denominator with the conjugate of the complex number (3 + i) which is (3 i). This gives 5 (3 i)/ (3 + i) (3 i) = (15 5i) / [(9 i2)] = (15 5i) /10 Hence the solution is 3/2 i/2. Example 2: Simplify the complex number fraction 6/ (2 + i)? Solution: Given is the complex number fraction 6 / (2 + i) Here the complex fraction has 6 in the numerator and (2 + i) in the denominator. To simplify multiply the numerator and denominator with the conjugate of the complex number (2 + i) which is (2 i). This gives 6 (2 i)/ (2 + i) (2 i) = (12 6i) / [(4 i2)] = (12 6i) /5 Hence the solution is 12/5 6i/5.

Basic Statistical Methods and Concepts

Basic Statistical Methods and Concepts Learn Everything from Probability to Wilcoxon Tests ChaptersWhat is Probability?How to Choose a Statistical TestWhen to Use Tests of AssociationTests of Comparison between MeansTests of Prediction using Linear RegressionTests for Nonparametric DataHow to Perform Statistical TestsLet’s face it, while data science was named the “sexiest job of the 21st century,” the majority of people still shudder at even the mention of statistics. The root of why this discipline has been so alienating throughout the course of its history can be found with its close relationship with mathematics.Whether you believe you can’t learn statistical analysis or are simply curious to learn more about it, this guide will help get you started by laying out the core introductory concepts.At the heart of statistics are the five essential concepts of statistics, and form the basis for data analysis. The first four can be dealt with without going into much detail about their equations:Mean: the average value, calculated as the sum of all observations over th e number of observationsMedian: the midpoint of the dataset, calculated by ordering all observations from least to greatest and taking the value directly in the middleVariance: the general spread of the data, calculated as the average of squared differences of the meanStandard Deviation: also a measure of spread, calculated by taking the square root of the varianceCompute statistical data easily | Photo by Jorge FranganilloMuch like witnesses in a detective novel, these four concepts start to tell you the story of a particular set of data because they are descriptive statistics. For example, if you look around at the people in any restaurant you find yourself in, it can be very difficult to build a narrative, or interpretation, about the kind of crowd you’re surrounded by based solely on appearance.Say, however, you are given information about their age, monthly income, level of education, gender, and taste of music. The first two concepts, the mean and the median, are both measur es of central tendency that can tell you whether your crowd is mostly twenty-somethings making their way through college or wealthy, elderly people that invest in hedge funds.The difference between when you use these concepts depends on the distribution of the variable that you’re measuring or, in this example, the amount of variability within the crowd. The more alike the crowd is, the more accurate taking the mean will be in telling your story; the more variation between the people are, the more accurate the picture you draw will be by taking the mean.The variance and standard deviation are both measures of variability and can tell you how different each observation in your data are from the average with regards to a specific variable.If you wanted to see how similar the crowd is in terms of age, you would start the computation by calculating the mean age and, by subtracting every individual’s age from it, find a number that tells you how far people are spread from the average . The standard deviation, on the other hand, gives you how  far or close your data is clustered around the mean based on a normal distribution.The standard deviation is exactly like the variance in terms of what it says about the spread of your data â€" in fact, the standard deviation is calculated by taking the square root of the variance. The difference lies in the fact that the standard deviation the descriptive measure that is easiest to report because it is in the same units as the original data, whereas the variance is not.You can test what you've learned in your statistics course so far by attempting some statistics practice problems online!Continuous: can take on any value, like heightDiscrete: are integers, like the number of childrenCategorical variables are qualitative and also fall under two distinct categories:Ordinal: has an obvious order, like a scale rating happiness from 1 to 10Nominal: has no meaningful order, like genderWhen to Use Tests of AssociationThese types of tests are meant for looking at the relationship between two variables. It is the closest you'll get to looking at causality between two variables. For example, you want to discover if there is an association between marital status and level of education. All of these test the strength of the association between two variables:Type of TestType of VariablesExamplePearson CorrelationTwo continuous variablesIf shoe size has an association with heightSpearman CorrelationTwo ordinal variablesHow strong of an association there is between happiness and economic statusChi-SquareTwo categorical variablesTo see whether gender and favorite color have any association AisvaryaData Analysis Teacher 5.00 (4) £25/h1st lesson free!Discover all our tutors AdeyemiData Analysis Teacher 5.00 (4) £25/h1st lesson free!Discover all our tutors AdenikeData Analysis Teacher 5.00 (4) £25/h1st lesson free!Discover all our tutors ThanushanData Analysis Teacher 5.00 (4) £25/h1st lesson free!Discover all our tutors GokhanData Analysis Teacher 5.00 (4) £30/h1st lesson free!Discover all our tutors OlawaleData Analysis Teacher £12/h1st lesson free!Discover all our tutors AisvaranData Analysis Teacher 5.00 (4) £25/h1st lesson free!Discover all our tutors Muhammad umairData Analysis Teacher 5.00 (2) £100/h1st lesson free!Discover all our tutorsTests of Comparison between MeansTests of comparison deal with looking at the differences between different variables by looking at the difference between their means.

For example, given data on gender, diet and income you can investigate whether a change in these leads to a change in height.Type of TestType of VariableExampleSimple Linear RegressionOne scale variable (dependent) with one or two scale variables (predictors)You want to see if and how well age and height predict weightMultiple Linear RegressionOne scale variable (dependent) with two or more scale variables (predictors)You want to see if and how well age, height, and income predict weightTests for Nonparametric DataThese tests should be performed when the data does not meet the assump tions for the other tests. For example, when the data does not follow a normal distribution and is highly skewed.Type of TestType of VariableExampleWilcoxon Rank-Sum TestTwo independent variablesBetween two different drugs, which one offers the best relief on two random, distinct groups of a populationWilcoxon Sign-Rank TestTwo related variablesBetween two different drugs, which one offers the best relief on the same group of patientsFriedman TestThree metric or ordinal variables (has to be either metric or ordinal)Three different ad ratings given by individuals in the same populationAddress your research question and experimental designHow to Perform Statistical TestsThere are several assumptions about the data you are using that are tied to each statistical test discussed. In order for the tests to run, be predictive and accurate, these assumptions must be held. Because the assumptions for different types of tests can be different, it is imperative to check them before you start t o model your data.The most common programs used for statistical analysis are:ExcelStataSASSPSSPythonRIf you are running tests for parametric data, there are four main assumption checks that your data will have to pass. However, it should be noted that each test has it's own different set of assumptions that should be checked beforehand, and that this list is simply the ones you will come across most often.AssumptionDescriptionIndependenceThe groups that make up the sample are independent of eachother.NormalityThe data in the set is are normal, meaning that there it follows a normal distribution.Homogeneity of varianceIf there are multiple groups in the data relating to your independent variable, they have the same variance.If you're looking for some extra help on these introductory subjects, there are many online resources you can use to build your skills. Tutoring websites like Superprof, or online webinar courses from R-bloggers can help you get started on crunching some numbers.
