In this chapter, you will learn how to test for the difference between groups on a single variable when you have three or more groups of data. A practical problem is presented that walks you through the Excel steps needed to generate the output for a one-way ANOVA test. You will learn ...
One-Way Analysis of Variance (ANOVA)Researchers use one-way analysis of variance in controlled experiments to test for significant differences among group means. This lesson explains when, why, and how to use one-way analysis of variance. The discussion covers fixed-effects models and random-...
This "quick start" guide shows you how to carry out a one-way ANOVA with post hoc tests using Stata, as well as how to interpret and report the results from this test. However, before we introduce you to this procedure, you need to understand the different assumptions that your data ...
