1. For the repeated-measures ANOVA, SSwithin treatments = SSbetween subjects + SSerror. A. True B. False 2. In the second stage of analysis for the repeated-measures ANOVA, individual differences are removed from the denominator of the F-ratio. A. True B. False
21. An ANOVA is used to evaluate the mean differences among three treatment conditions with a sample of n = 12 participants in each treatment. For this study, what is dfrotal?! a. 2 b. 11 C. 33 d. 35 22. Which of the following is expected if the null hypothesis is true for an analysis of variance (i.e., when the experimental manipulation has no effect)? a. SSbetween should be about the same size as SStotal b. SSbetween should be about...
A one-way analysis of variance produces SSTotal = 80 and SSWithin = 30. For this analysis, what is SSBetween?
Question 2 1 pts For an independent-measures ANOVA comparing four treatment conditions, dfbetween=3. True False Next For an analysis of variance comparing four treatment means with a separate sample of a participants in each treatment, the F-ratio will have df - 3.31, 8 True False Next →
The data below are from an independent-measures experiment comparing three different treatment conditions. Conduct a one-way ANOVA on the data. Use ANOVA Handout from the One-Way ANOVA module to guide your calculations. Tell help your error checking, I will tell you that SSTotal = 74 and dfTotal = 11.

The following data represent the results from an independent-measures study comparing two treatment conditions. Treatment One Treatment Two 7.4 5.4 5.4 2.4 7.5 4.7 6.3 5.9 6.6 5.3 8.7 3.7 6.8 2.3 Run the single-factor ANOVA for this data: F-ratio: p-value: Now, run the t test on the same data: t-statistic: p-value: Consider how these are the same or different.
The following data represent the results from an independent-measures study comparing two treatment conditions. Treatment Treatment One Two 2.5 7.2 5.2 7.6 5.8 4.4 6.3 4.5 4.7 5.2 4.8 3 Using technology, run the One-way ANOVA Test for this data: F-ratio: p-value: Now, run the Two Independent Sample t test on the same data: Note: Do this with "pooled variances" since one assumption we make with ANOVA is that the variances for each group are equal. t-statistic: p-value: Do you...
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
