WebTwo Ways to Get the p-Value in Excel The calculation of the p-value can be quite complex when done manually. The value is calculated from the deviation between the observed value and a chosen reference value, given the probability distribution of the statistic. A bigger difference between the values is indicated by a lower p-value. WebThis is a set of very simple calculators that generate p-values from various test scores (i.e., t test, chi-square, etc).
