Web30 jul. 2024 · To calculate Z-Score in Excel, you need to understand how Z-Score works in general through statistics. The formula that is used to calculate Z-Score is Z= (x-µ)/σ, where the arguments are: Z = Z score value. X = The value that needs to be standardized. µ = Mean of the given set of data values. σ = Standard deviation of the given set of data ... WebZ.TEST is calculated as follows when sigma is not omitted: Z.TEST ( array,x,sigma ) = 1- Norm.S.Dist ( (Average (array)- x) / (sigma/√n),TRUE) or when sigma is omitted: Z.TEST ( array,x ) = 1- Norm.S.Dist ( (Average (array)- x) / (STDEV (array)/√n),TRUE) where x is the sample mean AVERAGE (array), and n is COUNT (array).
