How Do You Find The Z-Score Using Microsoft Excel?
A Z-score, used in statistics, is the measurement of the number of standard deviations a number is above or below a mean. Z-scores are sometimes referred to as “standard scores” and “Z-values.” The Z-score is most often compared to samples to the standard normal deviate to determine how a set of data compares to standard numbers. The Z-score can be calculated by subtracting the mean from the raw score and dividing by the standard deviation. However, the Z-score can also be calculated using a function in Microsoft Excel. Open an Excel spreadsheet and enter your data in one column. Be sure to enter each piece of data for accurate results. Click any empty cell to place the result in. Click the “fx” button on the formula bar to open the “Function” window. Enter the number you wish to calculate the Z-score for in the “X” box. Enter a number or a cell reference where the number is located, such as “A5.” Enter the mean in the “Mean” box. If you do not know your mean, use the “AVERAGE” functio
