Single Factor Analysis of Variance (ANOVA) for Unrelated Samples (One-way ANOVA)
Assumption:
The measurements of the dependent variable are at least at the interval scale level.
The measurements of the dependent variable show normal distribution in each group.
The samples whose means are to be compared are independent.
Variance homogeneity.
Single Factor ANOVA for Related Samples
Single factor analysis of variance for related samples tests the statistical significance of the difference between the mean of two or more related samples.
Assumption:
The measurements of the dependent variable are at least at the interval scale level.
The measurements of the dependent variable show normal distribution in each group.
Difference scores show a multivariate normal distribution in the universe.
Variance homogeneity
