T statistic range
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 may be. WebThe T-Distribution or student T-Distribution forms a symmetric bell-shaped curve with fatter tails. Its mean comes out to be zero. The value of the distribution ranges between -∞ and …
