Normal distribution definition

Many of us were introduced to it when we first heard 'you will be graded on a curve' and now we can grasp how universally important it is.


Normal distribution is a probability distribution commonly used in Finance and other social sciences for statistical tests. There are several versions of the normal distribution, but the one called 'standard normal distribution' has a mean of 0 and standard deviation of 1 and is the default used to standardize data in spreadsheets and statistical analysis programming languages.

Synonyms: bell-shaped curve, Gaussian distribution, Gaussian function
