Jul 25 2019 A normal distribution of data is one in which the majority of data points are relatively similar meaning they occur within a small range of values with fewer outliers on the high and low ends of the data range.

When data are normally distributed plotting them on a graph results a bell-shaped and symmetrical image often called the bell curve. It shows you the percent of population. The mean and the standard deviation σ which plays key role in assets return calculation and in. An arbitrary normal distribution can be converted to a standard normal distribution by changing variables to so yielding.
