Fitting a discrete Uniform distribution backmore
Enter some figures (each should be greater than 5 but definitely bigger than 1) for Observed data in the top row of this table. Estimates of the mean of an assumed discrete Uniform distribution are then found, together with the Expected data and the calculation of S[O-E]²/E.
If S[O-E]²/E is greater than 14.067 then you can be 95% certain that your Observed data is not, in fact, from a Uniform distribution.
