there is a special tool in excel under data analysis, it outputs the tables automatically - it is an add it pack for excel I believe. If you don't have it then you can just count each observation manually or using the COUNTIF function
Then I just made charts and used the average and stdev functions in excel to calculate the mean and stdev.
this is the histogram pack: http://support.microsoft.com/kb/214269

Since this was a discrete probability distribution, I thought other probability functions in excel were to be used.
Thanks for your help.
