Time left 0:53:34 A 4 x 3 ANOVA has: a. 12 levels. b. 7 levels. c. Two factors one with 4 and one with 3 levels. Two levels each with 4 and 3 factors respectively. Time left 0:53:29 When comparing all pairwise differences between three means, which of the following tests does not effectively control for the inflation of the Type 1 error rate? a. The Holm-Bonferroni test. b. The Tukey test. c. The Dunnett's test. d. The t-test. Time left 0:53:24 When comparing a two-way factorial ANOVA to a series of one-way tests, the key advantage is that it incorporates: a. More powerful tests for each factor by removing the influence of the other factor. b. All possible comparisons between means. c. More powerful tests for each factor due to larger sample sizes. d. A test for the interaction between the two factors Time left 0:53:20 After performing a 2 x 2 between-subjects ANOVA to test the effect of drug type and dosage level on alleviating anxiety, a researcher obtained p = 0.055 for drug type, p = 0.010 for dosage level and p = 0.010 for the interaction between drug type and dosage level. The most of appropriate conclusion to make at this point, given that the level of significance was set at 0.05, is that the alleviation of anxiety is: a. Is not dependent on the drug type or dosage level. b. Is dependent on the dosage level. c. Is dependent on the drug type and dosage level d. Is dependent on the drug type. e naogo m Time left 0:53:15 In which scenario would a within-subjects design not be appropriate for analyzing the data? a. Analyzing the preferences of participants for different flavours of ice cream using a taste testing e procedure. b. Examining the effects of different teaching methods on the test scores of students in different classrooms. c. Comparing the anxiety levels of participants before and after a mindfulness meditation session. d. Investigating the differences in reaction times of participants under different lighting conditions
