In this simple example provided by Minitab, there is a statistical difference between the shipping centers, since the P-value is less than a standard threshold of 0.05 (5% risk of being wrong). We have three ecosystems (s 3), each with a sample size of ten hunter-gatherer groups (n 10). A One-way ANOVA is performed, since there is only one factor used in the analysis. General Linear Models: One-Way ANOVA 1 One-Way Analysis of Variance (ANOVA) and Multiple Comparisons For this example, we return to the population density of hunter-gatherers in three different forest ecosystems (data taken from Binford 2000).
The factor (independent variable) being evaluated is the shipping center. The variation being analyzed is the delivery times, which is the dependent response variable. An organization would like to know whether the differences in delivery times between the three shipping centers (Central, Eastern and Western) are statistically significant. Here is an example of the ANOVA summary results. The procedure works by comparing the variance between group means versus the variance within groups (error or noise in the experiment) as a way of determining whether the groups are all part of one larger population, or are separate (statistically different) populations with different characteristics. To perform an ANOVA, you must have a continuous response variable and at least one categorical factor with two or more levels.

ANOVA provides a statistical significance test of whether the estimated population means of 2 or more groups within each factor are equal.
