Can someone give a insight about how to compute p-value. I tried a lot and found that, look into the table and you will find the range for p-value, but instead of that I want to compute the exact p-value, perhaps I want to compute something like this:- http://www.graphpad.com/quickcalcs/pvalue1.cfm?CFID=11145312&CFTOKEN=81e59ca508e5ac24-68552A6D-1A4B-0BFB-435F96639648BF7A

I'm interested to know, if there is any formula, which can directly compute this.

Thanks a lot, in very-advance....for putting any valuable thoughts.

p-value is always associated with statistic. What is your statistic? What type of problem are you solving? – mpiktas Mar 1 '11 at 10:09
There are a lot of p-value questions here (for example here, you may find searching these to be useful – probabilityislogic Mar 1 '11 at 10:41
