HLT-362 exercise 36
Exercise 20.

Which patient scored the highest on the preoperative CVLT Acquisition? What was T-score ?
Patient 3 scored the highest with the T score of 63

Which patient scored the lowest on the postoperative CVLT Retrieval? What was the patients T score?
Patient 4 had the lowest score of 23

Did the patient in Question 2 have more memory performance decline than average on the CVLT Retrieval? Provide a rationale for your answer.
Yes they did. The memory performance decline was about a 9 point drop.The retrieval test for patient 4 was the about a drop of 21. This is almost double the amount. for the performance test. Mean =(47.8-38.2)=9.6 Patient 4 is 44-23=21 points.

What is the mean (x) and standard deviation (SD) for preoperative T score for CVLT Acquisition? Mean=46.35 and the SD is 5.06

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 patient 5 was above the norm for the T-score =52 and the mean score for the preoperative retrieval norm group is =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?
The retrieval scores
Mean= 47.8 and SD=5.8
47.8+5.8=53.6 and
47.8-5.8=42 Answer is (42,53.6)

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?
Mean is =38.2 and the SD =9.0
38.2 + 9.0=47.2
38.2-9.0=29.2
The answer is (29.2,47.2)

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.
No, the size used for this study is too small
