Question

An organizational psychologist asks a sample of n = 10 employees in a company to rate their job satisfaction on an 11-point scale from 0 = very unsatisfied to 10 = very satisfied. She also asks their supervisors to provide ratings of the employees' job performance, to test the hypothesis that more satisfied employees do better work. The raw scores for the job satisfaction variable are as follows: 8, 7, 3, 5, 1, 6, 6, 7, 9, 10. (a) What type of research method is the researcher using? Briefly explain your answer. (b) Does the job satisfaction variable have the properties of interval or ratio levels of measurement? For each of these two levels of measurement, briefly explain why (or why not). (c) Compute (a) the mean; (b) the variance; and (c) the standard deviation.
