For example we might want to know if three different studying techniques lead to different mean exam scores. A one way anova is used to determine how one factor impacts a response variable. A tukey post hoc test revealed significant pairwise differences between fertilizer types 3 and 2 with an average difference of 0 42 bushels acre p 0 05 and between fertilizer types 3 and 1 with an average difference of 0 59 bushels acre p 0 01.
Normality each sample was drawn from a normally distributed population.
For the results of a one way anova to be valid the following assumptions should be met. The two most common types of anovas are the one way anova and two way anova. Equal variances the variances of the populations that the samples come from are equal. A tukey post hoc test revealed significant pairwise differences between fertilizer types 3 and 2 with an average difference of 0 42 bushels acre p 0 05 and between fertilizer types 3 and 1 with an average difference of 0 59 bushels acre p 0 01.
