Select one: a. 27 b. 2 c. 30 d. 3 4-When computing the degrees of freedom for ANOVA, how is the within group estimate calculated? Note: N=sample size; k=number of groups Select one: a. n-1/k b. N–k c. k-1 d. n-1 5-A factorial ANOVA includes this many treatment factors Select one: a. only three or more b. only one c. only two d. more than one 6-When your research questions calls for you to examine the differences in group means among three or more groups, which of the following would be the appropriate procedure? Select one: a. Pearson correlation b. Dependent sample t-test c. Analysis of variance d. Regression 7-There are several types of ANOVA Select one: True False 8-Which of the following would be an example of a design that examines the effects of gender and region of residence (northeast, south, mid-west, west)?

Select one: a. 27 b. 3 c. 2 d. 30 10-If you wanted to examine whether the level of parental involvement differs based on students’ grade in school (i.e. 1st, 2nd, 3rd, etc.), what is the dependent variable of interest? Select one: a. parents b. students c. level of parental involvement d. grade level 11-When interpreting F (2, 27) = 8.80, p < .05, how many groups were examined? Select one: a. 3 b. 27 c. 30 d. 2 12-The Analysis of Variance tests the difference between two or more means Select one: True False 13-The variability within groups is due to Select one: a. chance b. the F ratio c. the level of the dependent variable d. the grouping factor 14-The ANOVA is like an extension of Select one: a. the F-test b. regression c. correlation d. the t-test 15-ANOVA uses the Select one: a. F-test b. p-test c. r-test d. t-test
