Is The One Way Anova Test Robust. The one way anova can be generalized to the factorial and multivariate layouts as well as to the analysis of covariance. Is the test robust.
The one way anova can be generalized to the factorial and multivariate layouts as well as to the analysis of covariance. The test statistic to be used is a weighted sum of squares similar to the welch 1951. What are the requirements to perform a one way anova.

The one way anova s f test is robust for validity against nonnormality but it may not be the most powerful test available for a given nonnormal distribution although it is the most powerful test available when its test assumptions are met. The one way anova is considered a robust test against the normality assumption. The within sample variability must be less than the combined variances of each group b. Revised on january 7 2021.
