One of the psychologist's findings is that 1 year after the workshop, a sample of 49 job seekers who received training on using the Internet to find job listings scored an average of 6.5 as measured on a 9-point job-search satisfaction scale, with a standard deviation of 1.2. The typical job seeker scores 5.8 points. The psychologist finds that the estimated Cohen's d is the t statistic is 4.12, and r2 is Using Cohen's d and Cohen's guidelines for interpreting the effect size with the estimated Cohen's d, there is a treatment effect. Using r2 and the extension of Cohen's guidelines for interpreting the effect treatment effect. (Hint: When using Cohen's guidelines for interpreting the size using r2, there is a effect size, if the value lies between two categories, then specify the range covered by both categories, for example, medium to large.) Another one of the psychologist's findings is that a sample of 144 job seekers who received training on interview skills worked more than 30 hours an average of 6.9 months in the last year, with a standard deviation of 2.5. The typical job seeker works 6.4 months. He finds that the estimated Cohen's d is the t statistic is 2.38, and r2 is . Using Cohen's d and Cohen's guidelines for interpreting the effect size with the estimated Cohen's d, there is a effect. Using r2 and the extension of Cohen's guidelines for interpreting the effect size with r2, there is a treatment treatment effect.
