hope someone can help me out with some stats for a data set I have- I originally thought it was easy but I think I'm over complicating everything in my head.
Ok so for example- I'm looking at the body length of dogs. I've taken measurements of 20 individuals of each breed and I've done this for 10 breeds. I now want to see if the measurements I've taken for each breed are a good representative of the actual breed- so I think I want to see if the variance for each breed is significant and then decide overall if all these variances are significant so that I can tell when I compare the breeds if I've actually got means that are representing the breed.
Still confused about how (or if its possible) I can tell if the variance within the breeds is significant. Would performing a stats test on the coefficients of Variance work?
