younger siblings seem to be quite the procrastinators. Decide to do some research on why and I found that some researchers think birth order has something to do with it. Intrigues by that idea, I collected data from several participants. I ask them their birth-order (first-born, middle-born, or last-born) and then have them complete the General Procrastination Scale (Lay, 1986). Scores on this measure range from 20 to 100 with higher scores representing higher procrastination and lower scores representing lower procrastination. Based on my prior research, I hypothesize that last-born participants are more likely to procrastinate than first-born or middle-born participants. Using SPSS, help me test my hypothesis by conducting the appropriate analysis. For post hoc test, select Tukey. Once you’ve conducted the analysis, answer the following questions.  Below, I have included images from SPSS.

Using your output, choose the correct answers for each blank. Note: any p-values that = .000 in SPSS were rounded to p < .001.

Based on the output, first-borns (a. did not significantly differ on, b. had significantly higher, or c. had significantly lower) procrastination scores compared to last-borns, (a. p=.37, b. p<.001, c. p=.005, or d. p=.602).

9) Using your output, choose the correct answers for each blank. Note: any p-values that = .000 in SPSS were rounded to p < .001.

Based on the output, middle-borns (a. did not significantly differ on, b. had significantly higher, or c. had significantly lower) procrastination scores compared to last-borns (a. p=.005, b. p=.602, c. p=.371, or d. p<.001
