Levene's test is a common test used to determine if the variances of two groups are equal. This test is often used as a preliminary test before running a t-test or ANOVA to ensure that the assumption of equal variances is met. The independent samples t-test is used to compare means between two groups, the paired sample t-test is used to compare means within the same group, and the one-sample t-test is used to compare a sample mean to a known population mean.
