I have values representing time taken to execute one request on server. Could somebody advise what type of distribution it is? I think that normal distribution but I am not really sure about it.
Thanks for your responses in advance.
UPDATE
Example situation: Consider you have collection of n values (from measurement process) representing time taken for i-th request to be executed on the server (i from 1 to n). What is the probability distribution of this time? (I know that it can be estimated applying input analysis methods, but in reality I don't have these values, I have only mean and deviation of them). In general, is it Gamma? Is it Normal? Or something else?
