# How to use the Excel STANDARDIZE Function

To get the normalised score (Z-score) of the value in the data set having mean (Average) and standard daviation of the data, we use the below formula in mathematics.

Z-score = (Value - Average) / (Standard deviation)

The STANDARDIZE function is a statistical function function. It takes returns a normalized value (z-score) for the values of the data
Syntax:

=STANDARDIZE (value, mean, standard_deviation)

Value : value to be normalised
Mean : Average of values
Standard_deviation : Standard deviation of the data
Let’s understand this function using it in an example. Here we have scores of the students and we need to find the Z score for the data.

For mean, we will use the AVERAGE function and For Standard deviation, STDEV.P function.

Use the formula:

=STANDARDIZE(A2, AVERAGE(A2:A12), STDEV.P(A2:A12))

A2 : value to be normalised
AVERAGE(A2:A12) : mean of the data
STDEV.P(A2:A12) : Standard deviation of the data As you can see the Z-score and its formula in adjacent cell from the above snapshot.

Copy the formula in other cells using shortcut key Ctrl + D As you can see the normalised value (Z-score) for the data.
