|
The observations are obtained independently and randomly from the population
|
|
|
The dependent variable is normally distributed
|
|
|
The independent variables are normally distributed

Variances are homogeneous for the dependent variable across each group in the population

Explanation:
Detailed explanation-1: -Potential assumption violations include: Implicit factors: lack of independence within a sample. Lack of independence: lack of independence between samples. Outliers: apparent nonnormality by a few data points.
Detailed explanation-2: -ANOVA assumes that the data is normally distributed. The ANOVA also assumes homogeneity of variance, which means that the variance among the groups should be approximately equal. ANOVA also assumes that the observations are independent of each other.
