An industrial/organizational psychologist has been consulting with a company that runs weekend job-seeking workshops for the unemployed. She collected data on several issues related to these workshops and, after conducting statistical tests, ottained statistically significant findings. She needs to find a way to evaluate effect size so that she can make recommendations to the company. One of the psychologist's findings is that one year after the workshop, a sample of 81 job seekers who received training on resume writing worked more than 30 hours per week an average of 8.7 months in the last year, with a standard deviation of 4.1. The typical job seeker works 7.4 months. The paychologist firds that the estimated Cohen's d is_ , the t statistic is 2.83, and ra Using Cohen's d and Cohen's guidelines for interpreting the effect size with the estimated Cohen's d, there is a effect. Using ra and the extension of Cohen's guidelines for interpreting the effect size using ra, there is a treatment treatment effect. (Hint: When using Cohen's guidelines for interpreting the effect size, the value lies between two categories, then specity the range covered by both categories, for example, medium to large.) Another one of the psychologists findings is that a sample of 81 job seekers who recelved training on dressing for interviews scored an average of 8.1 as measured on a 9-point job search motivation scale, with a standard deviation of 0.8. The typical job secker scores 7.4 points. the t statistic is 7.78, and ra is v.
