Summary
Students are guided through learning about comparing the means of two groups / levels using a t-test. The differences between a paired samples t-test and an independent samples t-test are reviewed along with the statistics’ assumptions. When two independent groups do not have equal variances, students are coached through completing a Mann–Whitney U test. Students are also guided through creating charts that can accompany their results in SPSS or R.
