There may be more answers discussed within the BioStats chapter, but they were hard to find bc they are embedded in the notes. If you post the page numbers, I can try to find more. Hope this helps.

pg 149 Descriptive Stats Example

Sample Data Set Mean = 60.8 Median = 61 Mode = 65

Std Deviation = no answer given, will not be expected to calculate

Range can be reported as either 87 - 46 or 41

pg 154-155 Rosuvastatin vs Simvastatin

Which is the most appropriate stat test to determine baseline differences in

A) Sex: Chi Squared

B) LDL: Independent t test aka 2 sample

C) % smoker vs. non-smoker: Chi Squared

Which is the most appropriate test to determine:

A) Effect of rosuvastatin on LDL: Wilcoxen Signed Rank Sum

Very confusing to the group. The key here (as explained) is that the samples are Paired. The measurements in the rosuvastatin group at baseline and compared against the same patients again at the 3 month mark.

B) The primary endpoint: 2 Sample t test

pg 158 Regression example

8c. i. Parametric, continuous values

ii. 31% of variability in Factor Xa conc. is explained by the Enox dose

iii. For 2mg ~ 0.5 U/mL; Cannot predict 3.75 because it is outside range of the experiment
