6.5.3.1 ANOVA
This template is for one-way ANOVA tests. It is in the Stats category. For information on accessing this template, see the
Templates : Accessing section. For more on using templates in general, see the Templates : Using the Templates
section.
Description
This template tests the equality of population means for 2 to 20
populations, assuming independent samples from normal populations
with a common variance. The null hypothesis in this one-way analysis of
variance is that all the population means are equal. The alternative is
that at least two of the means differ from each other.
Variables
· Data 1-20: between 2 and 20 data sets are chosen for comparison.
· F: F-test statistic.
· p: probability value or observed significance level of the test.
· Factor df: factor (or treatment) degrees of freedom.
· Factor SS: factor (or treatment) sum of squares (SSTr).
· Factor MS: factor (or treatment) mean square (MSTr).
· Error df: error degrees of freedom.
· Error SS: error sum of squares (SSE).
· Error MS: error mean square (MSE).
· Sxp: pooled standard deviation.
Example
Given the following data:
