The one-way analysis of variance (ANOVA) is used to determine whether there are any statistically significant differences between the means of two or more independent (unrelated) groups (although you tend to only see it used when there are a minimum of three, rather than two groups).
In this tutorial, we’ll look at how to perform a one-way analysis of variance (ANOVA) for independent groups in SPSS, and how to interpret the result using Tukey’s HSD.
A one-way ANOVA is used to determine whether or not there is a statistically significant difference between the means of three or more independent groups. This type of test is called a one-way ANOVA because we are analyzing how one predictor variable impacts a response variable.
