How To Find a Z-Score In Excel

To find a Z-Score in Excel, you can use the "STANDARDIZE" function. Here is a step-by-step guide:

  1. Enter your data into a column in Excel.

  2. Calculate the mean and standard deviation of your data using the "AVERAGE" and "STDEV.S" functions, respectively. Enter these functions in separate cells.

  3. In a separate cell, use the "STANDARDIZE" function to calculate the Z-Score of a particular value. The syntax of the function is: =STANDARDIZE(x, mean, standard_dev) Replace "x" with the cell containing the value you want to find the Z-Score for, "mean" with the cell containing the mean of your data, and "standard_dev" with the cell containing the standard deviation of your data.

  4. Press "Enter" to calculate the Z-Score of the value.

  5. To find the Z-Scores of multiple values at once, copy the formula to the cells below.

The Z-Score represents the number of standard deviations a particular value is from the mean of the data set. A positive Z-Score indicates that the value is above the mean, while a negative Z-Score indicates that the value is below the mean. Using the "STANDARDIZE" function in Excel can help you to quickly and accurately calculate Z-Scores for your data.
