Anova

By Roger Hansen | Sep 02, 2016 12:09PM CEST

Can I use an ANOVA on samples with wildly different sample sizes?
Sample 1 = 60
Sample 2 = 26
Sample 3 = 18

What is the best method to determine a difference in the means of the test scores?

Dear Roger,

XLSTAT can handle both unbalanced and balanced data so yes different sample sizes can be managed within it.

For the best method to test difference in means, ANOVA an t-test give good results if your data are distributed following a normal distribution.

To choose the appropriate test for your analysis, please follow the guide linked below:
