The PV (Present Value) function in Excel 2013 is found on the Financial button’s drop-down menu on the Ribbon’s Formulas tab (Alt+MI). The PV function returns the present value of an investment, which is the total amount that a series of future payments is worth presently.

Calculate P Value In Excel Formula
A P-value is a measure of the statistical significance of a statistical result. Statistical significance addresses the question: 'If, in the entire population from which this sample was drawn, the parameter estimate was 0, how likely are results as extreme as this or more extreme?' That is, it provides a basis to determine whether an observation of a sample is merely the result of random chance (that is, to accept the null hypothesis) or whether a study intervention has in fact produced a genuine effect (that is, to reject the null hypothesis).
