February 13th Questions

Q1) Rather than normalising, would there be an advantage to only scaling or centring the specific scores. Q2) Could we perhaps look into a between vs. within physician effect for the scores as a method to better understand the differences. Q3) Should we consider the reliability of the scores when carrying out analyses.

Q1) For example 1 is the scatterplot of the correlations more informative than the boxplot? Q2) In example 2 since we have just 40 patients can be use a non parametric test to understand the agreement? Q3) For the last example will taking proportions be effective?
