Question

ANOVA requires 2 assumptions. One is ______. the other is _______ .

Answer 1

Solution:

There are main three assumptions of ANOVA:

1) Normality: The distribution of residuals should be normal.OR sometimes in full statement,

All the response variables within the k populations follow a normal distributions.

2) Independent samples: That is the samples associated with each population are randomly selected and are independent from all other samples.

3) Equality of variance (homoscedasticity): The response variable within each of the k populations have equal variances.

Most of the time Normality and equality of variance must follow.

Hence, ANOVA requires 2 assumptions. One is Normality and the other is homoscedasticity.
