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 α = .05) to determine which treatments differ from which other treatments. Also, compute the percentage of variance explained by the treatment effect (η2). Conclude with an appropriate summary describing what you found. Be sure that the statement includes/refers to some descriptive statistics and clearly states the outcome of any hypothesis and post-hoc tests you conducted.

Participant: 1, 2, 3, 4

Treatments A: 6, 4, 4, 6

B: 3, 4, 2, 3

C: 3, 2, 0, 3

D: 0, 2, 2, 0

The following data were collected from a repeated-measures study: Determine if there are any significant differences among the four treatments. Use a .05 level of significance. Remember to; 1) State the null hypothesis, 2) Show all of your calculations, 3) Make a decision about your null hypothesis, 4) Make a conclusion including an APA format summary of your findings (include a measure of effect size if necessary), and 5) Indicate what you would do next given your findings.

(Chapter 14) The following data were obtained from a repeated-measures study comparing three treatment conditions. a. Use a repeated measures ANOVA with α=.05 to determine whether there are significant mean differences among the three treatments. (Hint: start by filling in the missing values on the table below). Be sure to show all formulas with symbols (and plug in numbers), steps, processes and calculations for all steps and all parts of all answers. b. Compute n2, the percentage of variance accounted...

5. Consider the following data from an independent measures study: Treatment 1 Treatment 2 n = 4 n = 4 mean = 4 mean = 11 SS = 96 SS = 100 Is there a evidence for a treatment effect? (α = .05, two tails). 6. A sample of n = 16 difference scores from a repeated measures experiment has SS = 440. The average difference score is 3. For a two-tailed test, α = .05, is this a...
