THE LOGIC OF ANOVA ANalysis Of VAriance (commonly abbreviated as ANOVA)‚ more specifically‚ we will take up an application known as one-way ANOVA. Many statisticians think of ANOVA as an extension of the difference of means test because it’s based‚ in part‚ on a comparison of sample means. At the same time‚ however‚ the procedure involves a comparison of different estimates of population variance—hence the name analysis of variance. Because ANOVA is appropriate for research involving three or

Assumptions * Dependent variable is either interval or ratio (continuous) * The dependent variable is approximately normally distributed for each combination of levels of the two independent variables. * Homogeneity of variances of the groups formed by the different combinations of levels of the two independent variables. * Independence of cases (this is a study design issue and is not addressed by SPSS).

Wk 4‚ DQ1 How would you explain the analysis of variance‚ assuming that your audience has not had a statistics class before? When one does a study of data‚ generally this implies an evaluation of the "mean" or average of that data. .i.e. What is the average time it takes a 5th grader to complete his final math exam? A t test is used to test differences between two means. i.e. the mean of the experiment group vs a control group. An ANOVA test‚ on the other hand‚ is indicated when there are
