One-way ANOVA tests whether the means of three or more independent groups are statistically different, by comparing variance between groups to variance within groups.

Stapsgewijze handleiding

1. 1F = MS_between / MS_within
2. 2MS_between = SS_between/(k−1)
3. 3MS_within = SS_within/(N−k)
4. 4Large F → group differences unlikely due to chance
5. 5Follow up significant ANOVA with post-hoc tests
