Question
eip between two variables. d. It describes the strength of the association between two variables. You will increase your chance of rejecting the null hypothesis and finding a significant difference between treatments in a one-way independent measures ANOVA problem if: (3 points) 2. arthe variance within groups is large. the variance within groups is small. C.the sample size is small. the difference between treatment means is small. 3. A researcher reports that college participants, on average, consumed significantly different amounts junk food 1 week before, during, and after finals week (F (2, 38)-6.21, p0.05). Based on the results, state the number of participants in the study. (3 points) For an experiment comparing more than two treatments you should use analysis of variance rather separate t tests because: (3 points) a. you are less likely to make an error in computations of ANOVA. a test based on variances is more sensitive than a test based on means. c. ANOVA has less risk of Type I error. d. ANOVA has less risk of Type II error. Table 2:Gender and Stress on DIS Table 1: Gender and Stress on DISTRESS 4.0 3 5Explanation / Answer
It is given that F (2,28) = 6.21
df1 = k - 1 = 2, where k is the number of columns. Therefore k = 3
df2 = 28 = N - k, where N is the total number of participants.
N - 3 = 28
Therefore N = 31
