Random Distributions
Normal, binomial, Poisson, uniform, and other distributions β and when each describes real data.
Normal (Gaussian) distribution
Slide 1 / 5The normal distribution is the classic bell curve: most values cluster around the mean, and fewer appear further away. Heights, measurement errors, and test scores roughly follow it.
rng.normal(loc=170, scale=10, size=1000)
β’ loc β the mean (the peak's center). β’ scale β the standard deviation (the spread). β’ size β how many values.
About 68% of values fall within one standard deviation of the mean, and 95% within two.
