Question 109

A psychologist examined the relative effectiveness of 2 therapy techniques for the treatment of seasonal depression.A sample of N=5 individuals who display moderate winter depression participated.Each subject was exposed to both light therapy and traditional cognitive therapy at different times.Treatments were counterbalanced to control for order effects.Following their treatment a survey was given measuring depression level.Therefore the dependent variable is a measure of depression after therapy via a questionnaire (1=not depressed 2=some depression 3=neutral 4=not depressed 5=happy. a. b.Is there a significant difference in the effectiveness of light therapy compared with cognitive therapy? Use a nondirectional correlated groups t-test with the alpha set at 0.05. c.Compute the value of eta-squared.Do your results indicate a weak,moderate or strong effect? d.Discern the nature of the relationship between the types of therapy.Which therapy is more effective? e.Write an APA results section to the data above.Remember to include the means and Standard deviations.

Question 113

Dr.August is investigating whether or not women have more job satisfaction after they are given praise or a gift card (different levels or rewards).She has recruited 10 women from Intel and for 6 months the women received praise then the next 6 months they received a gift card.The conditions were counterbalanced and a survey on job satisfaction was distributed following the treatment conditions or every 6 months until the research was completed.After finishing her study Dr.August was busy writing a grant,therefore she has asked you to analyze her data below.Please note the survey was based on 1-5 Likert scale with high scores indicating high job satisfaction and low score indicating dissatisfaction. Should the confidence intervals be included in the results section?
