- STATISTICS
The function to calculate z-score in Excel is STANDARDIZE(). This function accepts input parameters like data set, mean, and standard deviation. To calculate the mean and standard deviation, use the AVERAGE(x1 : xn ) and STDEV.S(x1 : xn ) functions in Excel.
The Z-score is a measure of how many standard deviations an observation or data point is from the mean.
It’s important for statistical analysis and research because it tells us whether a result is significant or not at a certain level of confidence.
