Calculate test statistic for hypothesis test

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. WebHypothesis Test. Here you will find everything about hypothesis testing: One sample t-test, Unpaired t-test, Paired t-test and Chi-square test. You will also find tutorials for non-parametric statistical procedures such as the Mann-Whitney u-Test and Wilcoxon-Test. mann-whitney-u-test and the Wilcoxon test
