Quizplus · Accepted Answer

Analysis of variance (ANOVA) is the appropriate statistical technique to examine the difference among the average scores of three or more unrelated groups. It compares the means of three or more independent groups to determine if there is a significant difference between them. Regression is used to examine the relationship between variables, while t-tests are used to compare means of two groups only.
