Workbook EXERCISE 20: Understanding T Scores

- Which patient scored the highest on the preoperative CVLT Acquisition? What was

his or her T-Score?

- Which patient scored the lowest on postoperative CVLT Retrieval? What was this

patient’s T-Score?

- 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.

- What is the mean ( X ) and Standard Deviation (SD) for preoperative T-score for CVLT

Acquisition?

- 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.

- 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?

- 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?

- 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.

- If a patient had a raw score = 30, what would his/her postoperative CVLT

Retrieval score be?

- Did patients demonstrate more postoperative memory decline among CVLT

Retrieval T scores than CVLT Acquisition T scores. Provide a rational for your answer.
