For what is one-way ANOVA used?
When comparing several population means, one-way ANOVA is employed.
The statistical approach of analysis of variance, or ANOVA, divides observed variance data into multiple components for use in additional tests. For three or more groups of data, a one-way ANOVA is used to learn more about the relationship between the dependent and independent variables.
The analysis of variance (ANOVA) method compares several population means, or the mean of a single variable over multiple populations.
It compares the means of two variables for populations that have been classified by a third variable.
