How do you find p-value on Excel?
As said, when testing a hypothesis in statistics, the p-value can help determine support for or against a claim by quantifying the evidence. The Excel formula we’ll be using to calculate the p-value is: =tdist(x,deg_freedom,tails)
Does Excel give p-value?
The p-value is used in correlation and regression analysis in Excel, which helps us identify whether the result is feasible and which data set from the result to work with. The value of the p-value ranges from 0 to 1. Unfortunately, Excel has no built-in method to find out the p-value of a given data set.

You’d type “=(C2 *SQRT(20-2)/SQRT(1-C2^2))” into a blank cell to find the t statistic. Now you can use this along with the “Tdist” function to find the P-value. In another empty cell, type “=TDIST([t statistic], [degrees of freedom], [number of tails])” to perform the relevant significance test in Excel.
