Mathematical Statistics. Lecture 8. Comparing two samples

Lecture 8 introduces the important techniques of two samples comparison. These techniques are used when performing the experiments in order to test the effect of a treatment Timeline: 00:00 Introduction and repetition 05:41 Comparing two independent samples 24:09 T-test for two independent samples with equal variances 34:34 Example 1:08:05 T-test for two independent samples with unequal variances 1:11:23 F-test for two population variances 1:18:23 Large sample inference 1:21:23 Paired t-test 1:27:34 Comparing two population proportions The course “Mathematical Statistics“ for the 2nd year bachelors in Economics Taught at BRICS institute, Irkutsk National Research Technical University, Spring semester 2022
