how can i check the geometric distribution

hello everyone,

I have to do a homework for the university. I need to find the geometric distribution in an array.

For example there are some data : 2, 3, 1, 4, 3, and each of these is the years between two earthquakes. I want to find, if this array follows geometric distribution.

thank you

Look at the Wikipedia page on this distribution and it will tell you how to estimate the parameter from your observations (it depends a little on which version of 'the' geometric you are thinking of).

Once you have estimated the parameter, use a chisquare test to check whether the observed frequencies of each value match the values predicted using that estimated parameter value.
