How do you find the p-value

WebFeb 3, 2024 · Below are steps you can use to calculate the p-value using the T.TEST function: Input your data samples into an Excel spreadsheet. Gather the number of tails and the type of t-test you want to perform. Use the formula =T.TEST (array 1, array 2, tails, type.) 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.
