2. Student's t-distribution - Wikipedia

   en.wikipedia.org/wiki/Student's_t-distribution

   In probability and statistics, Student's t distribution (or simply the t distribution) is a continuous probability distribution that generalizes the standard normal distribution. Like the latter, it is symmetric around zero and bell-shaped. However, has heavier tails and the amount of probability mass in the tails is controlled by the parameter ...

3. Student's t-test - Wikipedia

   en.wikipedia.org/wiki/Student's_t-test

   Student's t-test is a statistical test used to test whether the difference between the response of two groups is statistically significant or not. It is any statistical hypothesis test in which the test statistic follows a Student's t -distribution under the null hypothesis. It is most commonly applied when the test statistic would follow a ...

4. t-statistic - Wikipedia

   en.wikipedia.org/wiki/T-statistic

   Most frequently, t statistics are used in Student's t-tests, a form of statistical hypothesis testing, and in the computation of certain confidence intervals. The key property of the t statistic is that it is a pivotal quantity – while defined in terms of the sample mean, its sampling distribution does not depend on the population parameters, and thus it can be used regardless of what these ...

5. Statistics education - Wikipedia

   en.wikipedia.org/wiki/Statistics_education

   Statistics education is the practice of teaching and learning of statistics, along with the associated scholarly research. Statistics is both a formal science and a practical theory of scientific inquiry, and both aspects are considered in statistics education. Education in statistics has similar concerns as does education in other mathematical ...

6. Multivariate t-distribution - Wikipedia

   en.wikipedia.org/wiki/Multivariate_t-distribution

   0. In statistics, the multivariate t-distribution (or multivariate Student distribution) is a multivariate probability distribution. It is a generalization to random vectors of the Student's t -distribution, which is a distribution applicable to univariate random variables. While the case of a random matrix could be treated within this ...

7. Scott Freeman - Wikipedia

   en.wikipedia.org/wiki/Scott_Freeman

   Scott John Freeman (June 9, 1954 – July 23, 2004) was an American economist. He received his undergraduate degree from the University of Wisconsin–Madison and earned his Ph.D. from the University of Minnesota in 1983. Between undergraduate and graduate school he worked for the Peace Corps in Africa. Freeman started his professional academic ...

8. Noncentral t-distribution - Wikipedia

   en.wikipedia.org/wiki/Noncentral_t-distribution

   The non-central t -distribution is asymmetric unless μ is zero, i.e., a central t -distribution. In addition, the asymmetry becomes smaller the larger degree of freedom. The right tail will be heavier than the left when μ > 0, and vice versa. However, the usual skewness is not generally a good measure of asymmetry for this distribution ...
