# Thread: Discrete Uniform Distribution

1. ## Discrete Uniform Distribution

How do I test if a set of data fits a discrete uniform distribution?

Movie lengths: 69 78 93 104 100 145 88 76 68 73 99

Test if they fit the the discrete uniform distribution X~U(1,10)?
I was already to calculate expected values and use the chi squared test but got confused at my expectation being 0.1 for each length?

Surely you mean X ~ U(1, 100) ......?

If that is what it does mean there is no need for a test since the minimum is 69, and getting 11 out of 11 cases above 50 has probabilit <(1/2)^11~=0.0005
