Applied Statistics at Grand Canyon University Essay 1. Which patient scored the highest on the preoperative CVLT Acquisition? What was his or her T score? The 3rd patient scored 63 which is the highest CVLT T-score. 2. Which patient scored the lowest on postoperative CVLT Retrieval? What was this patientÃ¢â¬â¢s T score? The 4th patient scored the lowest on the postoperative CVLT Retrieval with a score of 23. 3. Did the patient in Question 2 have more of a memory performance decline than average on the CVLT Retrieval? Provide a rationale for your answer. Yes, because he scored 23 and the average is 38.2. 4. What is the mean ( X) and standard deviation (SD) for preoperative T score for CVLT Acquisition? The mean for preoperative T score for CVLT acquisition is 46.35, and the SD is 5.061, calculated using Excel auto sum function. 5. Is the preoperative Retrieval T score for Patient 5 above or below the mean for the norm of the group? Provide a rationale for your answer. The score for patient 5 on preoperative Retrieval T score (52) is above the mean for the norm of the group (47.36). 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 findings from this study be generalized to a larger population? Provide a rationale for your answer. No, because, according to our source, the sample size is too small to generalize the results for a larger population. 9. If a patient had a raw score = 30, what would his/her postoperative CVLT Retrieval T score be? Tscore=10X/SD+(50-10Xo/SD) Tscore=10(30)/1.414+(50-10(39.294))/1.414 Tscore=-15.729 10. Did patients demonstrate more postoperative memory declines among CVLT Retrieval T scores than CVLT Acquisition T scores? Provide a rationale for your answer No, the number of declines in both postoperative categories is the same(13).
