What statistical test should I use to compare two groups?When comparing two groups, you need to decide whether to use a paired test. When comparing three or more groups, the term paired is not apt and the term repeated measures is used instead. Use an unpaired test to compare groups when the individual values are not paired or matched with one another.
What test of statistics should be used if two sample means are given?The two-sample t-test (also known as the independent samples t-test) is a method used to test whether the unknown population means of two groups are equal or not.
What statistical tool can be use to compare the means of two groups of data?t-tests – used to compare the means of two sets of data. Wilcoxon U test – non-parametric equivalent of the t-test. Based on the rank order of the data, it may also be used to compare medians. ANOVA – analysis of variance, to compare the means of more than two groups of data.
