I use excel's tinv function to calculate p-value for msa analysis. I want to know whether I can manually calculate p-value. Are there some reference tables? or there is a direct formula?

First decide whether it is a one or two-tailed test.Miner, Please explain how to refer these tables for following values:
T-static=.1224
df=14
alpha=0.05
Thanks in advance
You have to work the table in reverse.
Find the 15 df column and follow it down until you bracket the t - value of 0.1224. In this case it is between the 1st and 2nd rows.
Next, interpolate both table t - values for 14 df. The method is the same as I illustrated in the previous post.
Go over to the two-sided tail probability and interpolate the probability for a t-value of 0.1224 using the two values that you just interpolate.
