Question

What are the sources of variation for one way between subjects ANOVA? Main effect of A and error variance Error variance and between group variance. Interaction effect and man effect of A Between group variance and F ratio Which is not an assumption for one-way between subjects ANOVA? Normality Random Sampling Homoscedasticity Independence A post hoc test is The number of standard deviations population mean shifted from the mean stated in the null hypothesis Computed to determine which pair of pairs of groups means significantly differ Computed to determine how much variability can be accounted for by levels of the factor The same as the F-Statistic When performing Turkey's HSD test to compare two treatments, if the difference between the means of those treatments exceed the calculated HSD, what do we conclude? There is a significant difference between the treatments There is no significant difference between the treatments. Nothing. The HSD for both treatments are calculated and compared to each other, without having to look at the means None of the above. For an F Ratio, what value is expected when the null hypothesis is true and why? O, because there is zero differences in treatment effect. 1, because the same variance would be measured in both parts of the ratio 2, because the variance between treatments would equal 2 and the variance within treatments would equal 1

Explanation / Answer

1) B) Error variance and between group variance.

2) B) Random sampling.

3) B) To determine which pairs of group means significantly differ.

4) A) There is a significant difference between the treatments.
