We can apply the min-max scaling in Pandas using the .min() and .max() methods.
In our previous example, the normally distributed random variable had a mean of 0 and a standard deviation of 1. A simple and commonly used plot to quickly check the distribution of a sample of data is the histogram. If the points in the plot roughly fall along a straight diagonal line, then the data is assumed to be normally distributed.
