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.
