Word on the street is that employees at your company are slacking off. You choose 102 employees and randomly assign half to a control group and half to an experimental group.
In the experimental group, employees are required to participate in a workshop focused on teaching how to use work time efficiently; the control group participates in no workshop.
After the workshop, you (secretly) measure the average amount of time each group spends on non-work related internet sites while they're on the clock.
You hope that the workshop is successful in decreasing the amount of time the experimental group spends on non-work related internet sites. (M (control group) = 1.3 hrs, SD = 0.5) (M (experimental group)= .90hrs, SD = 0.7), critical value = .05, p =.008.
What is the Independent Variable (IV) and its levels?
What is the dependent variable?
What does a high ‘score' on the dependent variable indicate?
What does a low ‘score' on the dependent variable indicate?
What is the mean/sd for each group?
What is N?
What is n for each group?
The research hypothesis predicts a significant difference in the DV for the groups being compared. Is this research hypothesis one-tailed or two-tailed?
What is the t-score for the t-test performed?
What are the df for the t-test performed?
Compare the t-score you computed to its cutoff (critical) value in the table. Are the t-test results significant?
Was the research hypothesis supported (accepted) or not supported (rejected) by your results?
