Exercise 20 HLT-362V
Class: HTL-362V-0104
EXERCISE 20
1. Which patient scored the highest on the preoperative CVLT Acquisition? What was his or her T score? Patient 3 scored highest on the preoperative CVLT Acquisition with a T score of 62
2. Which patient scored the lowest on postoperative CVLT Retrieval? What was this patient's T score? Patient 4 scored lowest on the postoperative CVLT Retrieval with a T score of 23
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; the average drop in CVLT Retrieval T scores was 9.6, representing a decline on average of 20% from baseline score. The drop in CVLT retrieval T scores for patient 4 was 21 points representing 52% from baseline score thus this patient had a memory decline that was twice that of the other patients.
4. What is the mean (X) and standard deviation (SD) for preoperative T score for CVLT Acquisition?
X= 45.9 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.
Patient 5 had a preoperative Retrieval T score above the norm group mean, since her T score = 52 and the preoperative retrieval norm group meant T score = 47.8
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?
68% of the scores for the preoperative CVLT Retrieval T scores were between (42, 53.6). Formula for 68% of the scores for a distribution is:
47.8 + 5.8= 53.6 47.8 – 5.8= 42
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?
68% of the scores for the postoperative CVLT Retrieval T scores were between (29.2, 47.2). Formula for 68% of the scores for a distribution is:
38.2 + 9.0= 47.2 38.2 – 9.0= 29.2
