WebJun 11, 2024 · There are four common ways to check this assumption in Python: 1. (Visual Method) Create a histogram. If the histogram is roughly “bell-shaped”, then the data is assumed to be normally distributed. 2. (Visual Method) Create a Q-Q plot. WebNormal Data Distribution. In the previous chapter we learned how to create a completely random array, of a given size, and between two given values. In this chapter we will learn how to create an array where the values are concentrated around a given value. In probability theory this kind of data distribution is known as the normal data ...
