The Python Scipy library has a module scipy.stats that contains an object norm which generates all kinds of normal distribution such as CDF, PDF, etc. The normal distribution is a way to measure the spread of the data around the mean. It is symmetrical with half of the data lying left to the mean and half right to the …
