Standardizing data is a process of transforming the data so that it has a mean of 0 and a standard deviation of 1. This is often done to ensure that all variables in the data have the same scale and the same distribution, which is important for many machine learning algorithms.
There are several ways to standardize data in Python, but the most common method is to use the StandardScaler class from the scikit-learn library. This class has a fit_transform() method that can be used to standardize data by fitting the scaler to the data and then transforming the data.
Once you have the necessary libraries, you can create an instance of the StandardScaler class and call its fit_transform() method. The fit_transform() method takes in the data as input, and returns the standardized data as output.
It’s important to note that standardizing data is not always necessary. It is typically only needed when the data contains variables that are on different scales, or if the data has a non-Gaussian distribution.
In addition to StandardScaler, python also provides other libraries like MinMaxScaler, RobustScaler, etc. These libraries can be used in the same way as StandardScaler to standardize the data in a specific way.
