. Create a scatter plot of the data b. Calculate r and r2 c. Report results in APA style. d. What do results mean? is the test significant?? Time Grade
As a student, you probably have noticed a curious phenomenon. In every class, there
are some students who zip through exams and turn in their papers while everyone
else is still on page 1. Other students cling to their exams and continue working until
the very last minute. Have you ever wondered what grades these students get? Are
the students who finish first the best in the class or are they simply conceding
failure? To answer this question, we carefully observed a recent exam and recorded
the amount of time each student spent working and the grade each student received.
Is there a relationship between the two?
