In a one-way ANOVA, how many independent variables are analyzed and how many means are compared?

Explanation:
One-way ANOVA analyzes a single factor that has multiple levels and compares the mean values of the dependent variable across those levels. The number of independent variables is one, and the number of means being compared equals the number of levels of that factor. Since ANOVA is used when you have three or more groups to test for differences among their means, the scenario described involves three or more means. If you only have two groups, a t-test can be used instead, because the F statistic in that case corresponds to the square of the t statistic.
