WebA normal distribution is called that because it's a very common distribution. Height for example has a normal distribution. If you measured the heights of all adult males and made a histogram of the data, the graph would have a bell curve with the peak of the bell curve at the average height. WebI want to look at monthly returns so let’s translate these to monthly: Monthly Expected Return = 8%/12 = 0.66%. Monthly Standard Deviation = 12%/ (12^0.5) = 3.50%. Let’s overlay the actual returns on top of a theoretical normal distribution with a mean of 0.66% and a standard deviation of 3.5%: Actual distribution vs. normal distribution.

WebEven though the normal distribution is theoretical, the distributions of many fields in the real world resemble the normal distribution. An example is the traditional bell curve for ranking students. Most students have average grades (the mean), while there are a few with the poorest grades and a few with the highest grades.
