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 mean ( X ) 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.
