Scenario: A study was conducted to look at whether caffeine improves productivity at work in different conditions. There were two independent variables (IVs). The first IV was email with two levels: 'email access' and 'no email access'. The second IV was caffeine also with two levels: 'caffeinated drink' and 'decaffeinated drink'. 30 different participants were randomly assigned into each condition. Productivity was recorded at the end of the day on a scale of 0 (I may as well have stayed in bed) to 20 (Wow! I got enough work done today to last all week). The group means on the productivity is presented in the table below. If you were to plot the results, what would the table look like?
