Workbook EXERCISE 20: Understanding T Scores

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? Provided a rationale for your answer.
4. What is the group 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 of 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 finding 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 score be?
10. Did patients demonstrate more postoperative memory decline among CVLT Retrieval T scores than CVLT Acquisition T scores. Provide a rational for your answer.
