Question
An occupational psychologist wishes to assess two different methods of manager supervision in influencing employee productivity. One method involves constant supervision by the workplace manager, while the second method involves intermittent (every 15 minutes) supervision by the workplace supervisor. To test whether constant versus intermittent supervision may influence workplace productivity differently, the psychologist first randomly selects 8 employees at his/her organization. Over the course of two weeks, each of the n = 8 employees is exposed to each of the two different supervision conditions. To control for any order effects, half of the participants were randomly assigned to receive constant supervision first, whereas the other half were randomly assigned to receive intermittent supervision first. After each week of supervision, the psychologist measures the productivity of each employee using a Productivity Scale. The scale ranges from a score of 0-35 (where higher numbers indicate higher levels of productivity). Below are results from the experiment in table format: a) State the Independent Variable in this research study, including its levels. b) State the Dependent Variable in this research study. c) What is the appropriate hypothesis test to conduct based on this research design? d) State the null and alternate hypotheses. e) Calculate the appropriate test statistic. f) Determine the critical region for this test at alpha = 0.01. g) What is the correct decision with respect to your hypotheses? Provide ONE reason why. h)Calculate ONE measure of effect size (r^2, d, OR a confidence interval) i) Interpret (in words) the result of this hypothesis test, including proper statistical notation.Explanation / Answer
Dear student,
According to Chegg guidelines, only the first four subparts are answered.
1, here, the independent variable is "Manager Supervision" which comes in two levels
a, Constant Supervision
b, Intermittent Supervision
2, Here, the dependent variable is "Employee productivity"
3, The appropriate test would be One factor ANOVA test.
4,
H0: There is no significant difference in employee productivity in constant and intermittent supervision.
H1: There is a significant difference in employee productivity in constant and intermittent supervision.
