distribution – normal

One of the most quintessential distributions is the Gaussian distribution or Normal distribution. Its probability density function resembles a bell. The centre of the curve is the mean of the data set. In the graph, 50% of values lie to the left of the mean and the other 50% lie to the right of the graph.
