A One-Way ANOVA, or analysis of variance, is a test used primarily in market research studies to compare the means of a single independent variable to that of the researcher's dependent variable. Before the age of modern technology, calculating a ANOVA was a complicated, time-consuming process, but today, it is relatively easy. If you have access to a TI-84 graphic calculator, and a complete, accurate data set, calculating a One-Way ANOVA is an easy way to see the results of your independent variable.
