WebFeb 7, 2024 · The built-in DAX functions to calculate the p-value are T.DIST for the left-tailed test, T.DIST.RT for the right-tailed test and T.DIST.2T for the two-tailed test. These functions require two parameters the t-stat and the degree of freedom. And here is the formula to dynamically interact with the different parameters. WebThe best way to calculate it manually is: t.value = (mean (data) - 10) / (sd (data) / sqrt (length (data))) p.value = 2*pt (-abs (t.value), df=length (data)-1) You need the abs () function because otherwise you run the risk of getting p-values bigger than 1 (when the mean of the data is bigger than the given mean)!
