EXERCISE 23 Questions to be Graded
Only 6 – 10 need to be answered.
6. Which of the following sets of variables has the strongest relationship?
a. Hamstring strength index 120°/s and the Hop index
b. Quadriceps strength index 60°/s and the Carioca test
c. Quadriceps strength index 120°/s and the Side step test
d. Quadriceps strength index 60°/s and the Triple hop index
7. In Table 5, two r values are reported as r = −0.498 and r = −0.528. Describe each r value in words, indicating which would be more statistically significant, and provide a rationale for your answer.
8. The researchers stated that the study showed a positive, significant correlation between Quadriceps strength indices and pre- and postoperative functional stability. Considering the data presented in the Table 5, do you agree with their statement? Provide a rationale for your answer.
9. The researchers stated that no significant relationship could be described between Hamstring strength indices 60°/s and functional stability. Given the data in Table 5, explain why not.
10. Consider the relationship reported for the Quadriceps strength index 120°/s and the Hop index (r = 0.744**, p = 0.000). What do these r and p values indicate related to statistical significance and clinical importance?
