WebHypothesis tests work by taking the observed test statistic from a sample and using the sampling distribution to calculate the probability of obtaining that test statistic if the null hypothesis is correct. In the context of how t-tests work, you assess the likelihood of a t-value using the t-distribution. WebThe T-Distribution is a measure of probability (p-value). It is used to find the statistical significance when the sample size is small, i.e., less than 30, with an obscure standard deviation. The mean of a T-Distribution is evaluated as zero, and the variance is derived as v/ (v-2), where v is the degree of freedom.
