Abstract

A one-way ANOVA (analysis of variance) compares the means of two or more groups for one dependent variable. A one-way ANOVA is required when the study includes more than two groups. (In other words, a t-test cannot be used.) As with t-tests, there is one independent variable and one dependent variable. Interval dependent variables for nominal groups are required. The assumption of normal distribution is not required.
