EXERCISE 20 Questions to be Graded
1. Which patient scored the highest on the preoperative CVLT Acquisition? What was his or her T score?
Female patient #3, with 63 T score is the highest preoperative acquisition.
2. Which patient scored the lowest on postoperative CVLT Retrieval? What was this patient's T score?
Male patient on #4 with 23 T score is the lowest postoperative Retrieval
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.
Yes, because pt. scored 44 and the average is 47.8 in preoperative CVLT Retrieval.
4. What is the mean () and standard deviation (SD) for preoperative T score for CVLT Acquisition? mean () = 45.9 and standard deviation (SD) = 5.2
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.
The T score of preoperative Retrieval of patient 5 is above norm group mean, since 52 is patient ‘s T score is 47.8 is the preoperative Retrieval mean.
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?
47.8+5.8= 53.6 and 47.8-5.8= 42 (42.53.6)
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? 38.2+ 9.0= 47.2 and 38.2-9.0= 29.2
(29.2, 47.2)
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.
Grove, states that the sample size was too small to permit generalization to the wider population of patients undergoing ATL. Despite the limitations the authors believed that
