Answer:
c. 3 treatments and 21 subjects
Solution:
We are given,
df1 = 2
that is,
df1 = Between degrees of freedom = number of treatments – 1
Number of treatments = df1 + 1 = 2 + 1 = 3
Now, we have
df2 = within df = 18
Total number of subjects = df1 + df2 + 1 = 2 + 18 + 1 = 21

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. You do not need to do post-hoc tests. Treatments 1 2 3 2 6 6 N = 12 4 6 10 G = 60 2 2 10 ∑X2 = 408 0 6 6 T = 8 T = 20 T = 32 SS = 8 SS = 12 SS = 16 2. A researcher reports an F-ratio with df =...

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...
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
3. Repeated-measures and matched-subjects experiments Aa Aa Repeated-measures experiments measure the same set of research participants two or more times, while matched-subjects experiments study participants who are matched on one or more characteristics. Which of the following are true for both a repeated-measures experiment and a matched-subjects experiment when used to compare two treatment conditions? Check all that apply. The researcher computes difference scores to compute a t statistic. □ If the researcher has n number of participants to use...
