Question

Select all that apply. The assumptions of ANOVA are?

A) Independence of observations
B) Homogeneity of variances
C) Normality of residuals
D) Correlation of predictors

Answer 1

The assumptions of ANOVA are independence of observations, homogeneity of variances, and normality of residuals.

Step-by-step explanation:

The assumptions of ANOVA are:

1. Independence of observations
2. Homogeneity of variances
3. Normality of residuals

Correlation of predictors is not an assumption of ANOVA.

In ANOVA, the independence of observations assumes that the observations within each group or treatment level are independent of each other. Homogeneity of variances assumes that the variability of the response variable is the same across all groups. Normality of residuals assumes that the residuals, which are the differences between the observed values and the predicted values, are normally distributed.
