Under what conditions is the one-way ANOVA test equivalent to, worst, and better than the t-test ?
Homework Answers
If there are only two groups then one-way ANOVA test and t-test are equivalent provided two population variances are equal.
If there are more than two groups, then one-way ANOVA is better than t-test provided population variances of all groups are equal. Becaue type I error rate for ANOVA is less than total type I error rate for all t tests required.
If there are only two groups and population variances are not equal, then t test for unequal variance (ie Walch's t test) is better than ANOVA.

One-way ANOVA test and t-tests compare means. Which of the following should you consider to select the One-way ANOVA over multiple t-tests when you have more than two groups? A. Multiple t-Tests will increase the likelihood of a Type I Error. B. Multiple t-Tests will decrease the likelihood of saying something is significant when it is not. C.
