College students were assigned to three study methods in an experiment to determine the effect of the study technique on learning. The three methods are; read only, read and underline, and read and take notes. The test scores are recorded below. Perform an analysis of variance, at the 0.05 level of significance. 12. Techniques Read and Read and take Read only underline notes 15 15 18 14 14 18 16 25 18 13 16

The goal of analysis of variance (ANOVA) is toa. detect differences in treatment variances (or variances for different populations).b. detect differences in treatment means (or means for different populations).c. analyze the average variances for different populations.d. analyze the variances of the variances for different populations.

Which of these is an advantage of using a transformed score when reporting the score of an individual case? a. Transformed scores will allow the mean score to be reported. b. Transformed scores will be reported on the nominal level. c. Transformed scores provide a context for the individual's score d. Transformed scores provide a measure of variability.

The Analysis of Variance. A research study compared beer consumed daily between 3 groups with 3 observations each. Group1 was UCB, Group 2 UCSD, and Group 3 UCI. Determine if there is a significant difference among the groups 5% level. Group1: UCB Group 2: UCSD Group 3: UCI The Results of this study are in the following table:                     Group1                           Group2                                    Group3 Sample         3, 4, 5                                3.2, 4, 4.2                             3, 4, 3.3 Mean           4.0                                    3.7                                         3.4 S^2               4.4                                    5.2                                         6.1   null and alternative hypotheses are Null hypothesis Ho :  There is a significant difference among the treatment group means  Alternative Hypothesis Ha : At least one group mean is different from other group means the average mean due to treatments are…
