We can normalize values in a dataset by subtracting the mean and then dividing by the standard deviation. This is also known as converting data values into z-scores.

To normalize the values in a given dataset, enter your comma separated data in the box below, then click the “Normalize” button:

Explanation: The mean value of the dataset is 4. The standard deviation is 4. Thus, to find the normalized value for each value in the dataset, we subtract by 4 and divide by 4.
