Statistical & Hypothesis Tests: Performing Two-sample T-tests & Paired T-tests

In situations where two independent samples are drawn from different populations or where paired samples are available such as in a before-after scenario two-sample and paired T-tests are needed respectively. Use this course to explore how two-sample T-tests can be used to test the null hypothesis that two independent samples have drawn from populations with equal means. Youll examine type I and type II errors and the use of paired samples T-tests. By the time you finish this course you will be able to test whether two samples – either drawn independently or explicitly linked – are drawn from populations with equal means.
