I would appreciate some advice from the list on handling paired data. I have
had unequal amounts of data from subjects. In a small pilot study of a course
for teaching communication skills, subjects were taped and scored for their
use of taught (micro)skills. Some managed to record the requested number of
consultations but some did not. I realise it is an error to treat each set of
data as an individual data point, should I average each subject's change scores,
but then this seems to overvalue the data for those who contributed fewer consultations?
Is it valid to average whole group scores to look for a global shift?
many thanks
