Quizplus · Accepted Answer

Analysis of variance (ANOVA) is the appropriate statistical technique to compare the means of three or more unrelated groups. It helps to determine if there is a significant difference in the means among the groups, taking into account the variability within each group. The t-test for independent samples can be used to compare the means of two unrelated groups. Regression is used to determine the relationship between two or more variables. T-test for dependent samples is used to compare the means of two related samples.
