Normal Distribution
The Normal Distribution is one of the most important distributions.
It is also called the Gaussian Distribution after the German mathematician Carl Friedrich Gauss.
It fits the probability distribution of many events, eg. IQ Scores, Heartbeat etc.
Use the random.normal() method to get a Normal Data Distribution.
It has three parameters:
loc - (Mean) where the peak of the bell exists.
scale - (Standard Deviation) how flat the graph distribution should be.
size - The shape of the returned array.
Example
from numpy import random
x = random.normal(size=(2, 3))
print(x)
Example
from numpy import random
x = random.normal(loc=1, scale=2, size=(2, 3))
print(x)
Visualization of Normal Distribution
Example
from numpy import random
import matplotlib.pyplot as plt
import seaborn as sns
sns.displot(random.normal(size=1000), kind="kde")
plt.show()
Note: The curve of a Normal Distribution is also known as the Bell Curve because of the bell-shaped curve.
