Re: Correlation Between Mean and Standard Deviation

The word "spread" caught my attention. That's what I think I mean. Both sets of my data have a theoretical minimum and maximum value of 0 and 1 respectively (it can't be more or less than that). What are being measured are the aesthetic values of different manifestations of two similar types of objects.

Since your range is restricted to lie between 0 and 1, you might
consider fitting a Beta distribution to the data. You can estimate
the Beta parameters from the sample mean and standard deviation. This
could provide more insight when comparing two data sets since the
parameters of a Beta
distribution tell you whether the data is increasing, decreasing, U-
shaped, convex, concave or unimodal.
