HLT 362V Exercise 20

1. Which patient scored the highest on the preoperative CVLT Acquisition? What was his or her T score?
2. Which patient scored the lowest on postoperative CVLT Retrieval? What was this patient’s T score?
3. Did the patient in Question 2 have more of a memory performance decline than average on the CVLT Retrieval? Provide a rationale for your answer.
4. What is the mean ( ) and standard deviation (SD) for preoperative T score for CVLT Acquisition?
5. Is the preoperative Retrieval T score for Patient 5 above or below the mean for the norm of the group? Provide a rationale for your answer.
6. Assuming that the distribution of the preoperative CVLT Retrieval T scores is normal, the middle 68% of the patients had T scores between what two values?
7. Assuming that the distribution of scores for the postoperative CVLT Retrieval T scores is normal, the middle 68% of the patients had T scores between what two values?
8. The researchers state that it appears that the functional integrity of the left temporal lobe, despite evidence of structural abnormality, plays a considerable role when it comes to memory outcomes following left ATL. Can the findings from this study be generalized to a larger population? Provide a rationale for your answer.
9. If a patient had a raw score = 30, what would his/her postoperative CVLT Retrieval T score be?
10. Did patients demonstrate more postoperative memory declines among CVLT Retrieval T scores than CVLT Acquisition T scores? Provide a rationale for your answer.

HLT 362V EXERCISE 23 Questions to be Graded    

1. What is the r value for the relationship between Hamstring strength index 60°/s and the Shuttle run test? Is this r value significant? Provide a rationale for your answer.
2. Consider r = 1.00 and r = -1.00. Which r value is stronger? Provide a rationale for your answer.
3. Describe the direction of the relationship between the Hamstring strength index 60°/s and the Shuttle run test.
4. Without using numbers, describe the relationship between the Hamstring strength index 120°/s and the Triple hop index.
5. Which variable has the weakest relationship with the Quadriceps strength index 120°/s? Provide a rationale for your answer.
6. Which of the following sets of variables has the strongest relationship?
7. Hamstring strength index 120°/s and the Hop index
8. Quadriceps strength index 60°/s and the Carioca test
9. Quadriceps strength index 120°/s and the Side step test
10. Quadriceps strength index 60°/s and the Triple hop index
11. 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.
12. 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.
13. 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.
14. 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?
