Mann-Whitney U Test [Simply explained]

What is a Mann-Whitney U Test? And how is it calculated? That's what we will discuss in this video. A Mann-Whitney U test tests whether there is a difference between two independent samples. An example: Is there a difference between the reaction time of women and men? But the t-test for independent samples does the same!?! It also tests whether there is a difference between two independent samples. The Mann Whitney U Test is the non-parametric counterpart to the t-test for independent samples. ► Load sample data set https://datatab.net/statistics-calcul... ► Online Calculator Mann-Whitney U-test https://datatab.net/statistics-calcul... ► Mann-Whitney U-test Tutorial https://datatab.net/tutorial/mann-whi... ► E-BOOK https://datatab.net/statistics-book 00:00 What is a Mann-Whitney U Test? 00:23 Mann-Whitney U Test vs. t-test for independent samples 02:07 Hypotheses Mann-Whitney U Test 02:25 Example Mann-Whitney U Test 02:43 Calculate Mann-Whitney U Test with DATAtab 03:47 Calculate Mann-Whitney U Test by hand 08:03 Mann-Whitney U Test with tied ranks #statistics #datascience #dataanalysis #dataanalytics #research #student #thesis #stats #researcher #science #datatab #SPSS #machinelearning
