# Question

A recent study examined how applicants with a facial blemish such as a scar or birthmark fared in job interviews (Madera & Hebl, 2011). The results indicate that interviewers recalled less information and gave lower ratings to applicants with a blemish. In a similar study, participants conducted computer-simulated interviews with a series of applicants including one with a facial scar and one with a facial birthmark. The following data represent the ratings given to each applicant.

a. Use a repeated-measures ANOVA with a = .05 to determine whether there are significant mean differences among the three conditions.

b. Compute h2, the percentage of variance accounted for by the mean differences, to measure the size of the treatment effects.

c. Write a sentence demonstrating how a research report would present the results of the hypothesis test and the measure of effect size.

## Answer to relevant Questions

One of the primary advantages of a repeated-measures design, compared to an independent-measures design, is that it reduces the overall variability by removing variance caused by individual differences. The following data ...A researcher measures three variables, X, Y, and Z, for each individual in a sample of n = 25. The Pearson correlations for this sample are rXY = 0.8, rXZ = 0.6, and rYZ = 0.7. a. Find the partial correlation between X and ...Does the regression equation from problem 21 account for a significant portion of the variance in the Y scores? Use a = .05 to evaluate the F-ratio. For the following scores, a. Sketch a scatter plot and estimate the Pearson correlation. b. Compute the Pearson correlation. Research indicates that playing a prosocial video game tends to increase prosocial behaviors (Greitemeyer & Osswald, 2010). In a similar experiment, participants were assigned to play a prosocial, a violent (antisocial), or ...Post your question
