How to Find P-Value? To calculate the p-value, you must first find the test statistic, a value which results from the particular test of significance (or hypothesis test) you use to analyze the data. Common tests of significance include the z-test, the t-test, and the χ2-test. ...
Statisticians can use Excel to quickly and easily calculate the p-value. Although Microsoft does not have any specific or direct formula for p-value in Excel, we can use functions like T.TEST and T.DIST for the calculation. Moreover, there is another method: Analysis ToolPak, that basically...
The P-Value in Excel is the probability value that denotes the extent, an observation or finding is statistically significant. And it ranges between 0 and 1. Users can use the P-Value to decide whether to accept or reject a null hypothesis while performing hypothesis testing during analyses an...
The ABS function adjusts the T value for a right-tailed test. The T and Z critical values differ from the T and Z values. We calculate the T and Z values from the sample statistic and population parameters. Then we compare those values with the critical values to determine the statistica...

Graphically, the p value is the area in thetailof aprobability distribution. It’s calculated when you run hypothesis test and is the area to the right of thetest statistic(if you’re running atwo-tailed test, it’s the area to the leftandto the right). ...
