Hi All,

I am a software developer who is after the algorithm for calculating chi-square and p-values to test for randomness of data.

I have gone through Knuth and was unable to understand a few bits.

Can any of you help me in understanding in how to calculate the above (I also need help with Runs-up and Runs-down tests).

Please try to use the least of Mathematical notations (I know I know it's a math forum)

My scenario is something like this:

I have a column of data with lets say 3000 rows. The Min value is 1 and Maximum value is 10. I understand that the degree of Freedom in this case would be 9. Now do I need to find out subtotals of each number i.e. how many times 1 has occurred and how many times and 2 and 3 and so on till 10. what do I need to do next????

Your help in this regard would be highly appreciated.

Regards,
Riz
