Two way ANOVA: A Two-Way ANOVA is useful when we desire to compare the effect of multiple levels of two factors and we have multiple observations at each level. Grand

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

compared to the other two groups means. In the case where there are more than two levels of the independent variable‚ the analysis goes through two steps; first‚ we will carry out an overall f-test to determine if there is any significant differences existing among any of the means. If we find that the f-score is statistically significant‚ then we will move on to step two of the analysis. In this second step we will compare two sets of means simultaneously in order to determine specifically where the significant
