Let's say I have a matrix where the underlying data is from the entire population. Let's say I also have a matrix where the underlying data has been sampled from population.
How would I analyze how well the the sample represents the population?
My gut instinct is to convert it into a row-col listing:
row col popvalue samplevalue 1 1 34.5 33.2 [...] i j 54.4 51.2
and then run ANOVA between the two. Does this sound right or is there a better way to measure this?
