What Standardize is
Standardizing is the process of transforming data so that it has a mean of 0 and a standard deviation of 1. This helps make the data more consistent and easier to compare across different measurements. The steps to standardizing data are as follows:
-
Calculate the mean of the data set.
-
Subtract the mean of the data set from each data point in the set.
-
Calculate the standard deviation of the data set.
-
Divide each data point in the set by the standard deviation of the data set.
By standardizing the data, the data can be compared across different measurements and the results will be more consistent.
Examples
-
Standardize data sets by subtracting the mean and dividing by the standard deviation in order to compare data points between different samples.
-
Standardize data points by mapping them to a common scale such as the Z-score to compare values between different distributions.
-
Standardize a categorical variable by changing it to a numerical representation so it can be used in statistical analysis.
