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 ...
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 ...
XIV; Students for Fair Admissions v. Harvard, 600 U.S. 181 (2023), is a landmark decision [1][2][3][4] of the Supreme Court of the United States in which the court held that race-based affirmative action programs in college admissions processes violate the Equal Protection Clause of the Fourteenth Amendment.

New Jersey v. T. L. O., [fn 1] 469 U.S. 325 (1985), is a landmark decision by the Supreme Court of the United States which established the standards by which a public school official can search a student in a school environment without a search warrant, and to what extent. The case centered around a student at Piscataway High School in ...
Family and friends are asking for the public's help in locating University of Texas doctorate student Frank Guzman, who along with his wife, Caroline Katba, has been missing since late July ...
The noncentral t-distribution generalizes Student's t -distribution using a noncentrality parameter. Whereas the central probability distribution describes how a test statistic t is distributed when the difference tested is null, the noncentral distribution describes how t is distributed when the null is false.
t. e. Student rights are those rights, such as civil, constitutional, contractual and consumer rights, which regulate student rights and freedoms and allow students to make use of their educational investment. These include such things as the right to free speech and association, to due process, equality, autonomy, safety and privacy, and ...
where t is a random variable distributed as Student's t-distribution with ν − 1 degrees of freedom. In fact, this implies that t i 2 /ν follows the beta distribution B(1/2,(ν − 1)/2). The distribution above is sometimes referred to as the tau distribution; [2] it was first derived by Thompson in 1935. [3]
