I would like some advice on a variation of a problem I had previously
Someone has data on 500 patients doctor A has been treating and 500
patients doctor B has been treating. There are scores on the patients
regarding symptoms, complications etc and we want to assess the
performance of doctor A from his 1st patient to the last, i.e. for
operative time we want to know if it has increased or not during the
time he has been seeing patients. I received some great advice from
you on linear regression, serial correlation etc.
My new questions are:
- If one randomly assigns the 500 patients of doctor A in 5 groups of
100 patients each, and wants to compare e.g. operative time between
these 5 groups, but if it is also necessary to control for variables
like age, would the appropriate method be ANOVA?
- If one wants to compare a group of doctor A with a group of doctor
B, I guess one should apply ANOVA here as well?
- And if we would like to compare the total performances of the two
doctors for a particular score, e.g. operative time, what would be an
appropriate method? Is it ANOVA again?
Thank you all
