Apr 19, 2024 · The normal distribution is a continuous probability distribution function also known as Gaussian distribution which is symmetric about its mean and has a bell-shaped curve. It is one of the most used probability distributions.
Jan 3, 2021 · How to plot a normal distribution with Matplotlib in Python ? Last Updated : 03 Jan, 2021. Prerequisites: Matplotlib. Numpy. Scipy. Statistics. Normal Distribution is a probability function used in statistics that tells about how the data values are distributed.
Dec 31, 2021 · However you can find the Gaussian probability density function in scipy.stats. So the simplest way I could come up with is: import numpy as np. import matplotlib.pyplot as plt. from scipy.stats import norm. # Plot between -10 and 10 with .001 steps. x_axis = np.arange(-10, 10, 0.001) # Mean = 0, SD = 2.
Draw random samples from a normal (Gaussian) distribution. The probability density function of the normal distribution, first derived by De Moivre and 200 years later by both Gauss and Laplace independently , is often called the bell curve because of its characteristic shape (see the example below). The normal distributions occurs often in nature.
