1. Patient 3 scored the highest on the pre-op CVLT Acquisition with a T score of 63.
2. Patient 4 scored the lowest on the post-op CVLT Retrieval with a T score of 23.
3. Yes patient 4 did have more of a memory performance decline than average his decline was from 44 to 23, a 21 point drop. The average drop in T scores was 9.6 representing a decline of 20% from the baseline, patient 4 almost doubled the average decline.
4. Mean: 45.9 Standard Deviation: 5.2
5. The pre-op retrieval score for patient 5 was above the mean for the norm of the group. Patient 5 T score was 52, the mean for the norm of the group was 48.25. Patient 5 was 3 points above the mean.
6. X=47.8 SD= 5.8 X+- SD
47.8+ 5.8= 53.6 47.8-5.8= 42
Answer: (42, 53.6)
7. X= 38.2 SD= 9.0 X+-SD
38.2+9.0= 47.2 38.2-9.0=29.2
Answer: (29.2, 47.2)
8. No, because the sample size is too small to generalize the results for a larger group of patients. The sample size was only 17, to generalize from such a small group would not be appropriate because in a larger group the results may vary and be different than it was in this small group.
9. T score=10(30)/9.0 + (50-10(38.2)/9.0) = 33.3 + (50-42.4) =40.9
10. Yes, there was more of a decline among the CVLT Retrieval scores than in the CVLT Acquisition scores. The post-op acquisition mean was only 39.0 with a standard deviation of 7.2, while with the retrieval mean was 38.2 with a standard deviation of 9.0. The difference was not significantly larger but there was a difference in
