What are the assumptions of a one-way ANOVA?
Posted May 19, 2022
Answer
The following assumptions are made when performing one-way ANOVA:
- The populations from which the samples are drawn have a normal distribution
- The samples are independent (chosen at random and on their own)
- Each group has the same variance (homogeneity of variance)
- Measurement of the dependent variable is at interval or ratio level
