An independent-measures research study with n=5 participants in each treatment produces sample variances of 8 and 10, and a 2-point difference between the two treatment means (i.e.,M - M2=2). Given this information, what is the value of Cohen's d? 2/2 2/3 ООО 6 219 2/18
An independent-measures study comparing two treatment conditions produces a t statistic with df = 18. If the two samples are the same size, how many participants were in each of the samples? a) 9 b) 10 c) 19 d) 20

For a research study comparing two treatment conditions, a repeated-measures design would require one score for each participant but an independent-measures design would require two scores for each participant. True or False
1. In analysis of variance, MS between-groups provides a measure of the total variability for the set of N scores, standard deviation, the overall mean for the set of N scores, differences among treatment means 2. An independent-measures research study compares three treatment conditions using a sample of n = 5 in each treatment. For this study, the three totals are, T1 = 5, T2 = 10, and T3 = 15. What value would be obtained for the grand mean,...
1. The following data represent the results from an independent-measures experiment comparing three treatment conditions. Use an analysis of variance with α = .05 to determine whether these data are sufficient to conclude that there are significant differences between the treatments.

QUESTION 19 For an independent-measures research study, what is measured by Cohen's dori?? a. Whether or not treatment means are significantly different b. The size of the difference between the two treatements OC. The risk of committing a Type I error d. Whether the difference between the two treatments is likely to have occurred by chance QUESTION 20 A researcher conducts an independent samplest test with df = 50. If the two samples are the same size, then how many...
