20. The following data summarize the results from an independent-measures study comparing three treatment conditions. M=2 M=3 M=4 n=10 T=20 n=10 T=40 In=10 T=30 s2=2.67 s²=2.00|s²=1.33 a. Use an ANOVA with a = .05 to determine whether there are any significant differences among the three treatment means. Note: Because the samples are all the same size, MSwithin is the average of the three sample variances. b. Calculate n to measure the effect siz for this study.

In a study performed on comfort food eating during times of stress, it was found that mean rated comfort food consumption level (on a scale from 1-20) for a group of students undertaking their exam period was 14. In comparison, a group of students who were not undertaking exams or examination preparation had a mean rated comfort food consumption level of 10. The pooled estimate of the population variance was 64. What is the estimated effect size (d) of the study? 0.80 0.06 0.50 2.00
