If a researcher reported an F-ratio with df = 3, 30 for a repeated measures ANOVA, then there were _____ conditions in the experiment and _____ total subjects. 4; 10 4; 11 3; 10 3; 11
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...
7. Assumptions underlying repeated-measures ANOVA Which of the following are assumptions underlying repeated-measures ANOVA? Check all that apply. The populations from which the samples were taken are normally distributed The population variances for each of the treatment groups (cells) differ.The population variances for each of the groups (cells) are equal. The values of the repeated variables are constant.
For a repeated-measures ANOVA, which of the following is computed differently, compared to an independent-measures ANOVA? a. total SS b. between treatment SS c. within treatment SS d. the denominator of the F ratio
A within-subjects design is to the whereas a between-subjects design is to the a. Repeated-measures ANOVA; One-way ANOVA. b. One-way ANOVA; Chi-square test for independence, c. One-way ANOVA; Repeated-measures ANOVA. d. Dependent samples t-test; Repeated-measures ANOVA

1) The following data were collected from a repeated-measures study investigating the effects of 4 treatment conditions on test performance. Determine if there are any significant differences among the four treatments. State the null hypothesis. If you determine a significant treatment effect, use Tukey's HSD test (overall a = .05) to determine which treatments differ from which other treatments. Also, compute the percentage of variance explained by the treatment effect (12). Conclude with an appropriate...
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
When assumptions are violated in repeated-measures ANOVA, a non-parametric test called Friedman’s ANOVA can be used in which situations? a. For any repeated-measures ANOVA design. b. When you have only one independent variable. c. When you have two or more independent variables. d. Never for repeated-measures ANOVA.
Imagine you have a repeated-measures design with 25 participants and want to compare the means of the two conditions. For condition 1 (or sample 1), the mean = 10 and the standard deviation = 10; for condition 2 (or sample 2), the mean = 15 and the standard deviation = 10; for the difference scores, the mean = 5 and the standard deviation = 5. What is the value of Cohen's d? 0.20 0.50 1.00 5.00
Recitation Exercise: Repeated Measures ANOVA Answer the following questions. You are allowed to work in groups, but everyone must show All of their work. Round to the hundredth decimal place at every step and Jeel free to attach an additional sheet of paper 1.) A researcher has randomly selected a sample of 5 adults to participate in a memory study. Each adult is exposed to different types of music to see if the presence of lyrics in the music influences...
