distributions are extremely important in statistics and are often used in the natural and social sciences for real-valued random variables whose distributions are not known (Casella and Berger, 2002). This essay will discuss the use of NormalDistribution in a business and in reallife.

possible values for P ( Z < z ) then we could calculate this since P ( −1 < Z < 1.5 ) = P ( Z < 1.5 ) − P ( Z < −1) .

In Extremistan, scalability is possible and variation within distributions is much less constrained than in Mediocristan. Wealth of individuals is an example of such an attribute distribution. In such a world, there exist distributions with...
was invented by GAUSS and therefore it called Gaussian Distribution also. However, since 85-90% of the reallife problems can be solved using this method, it came to be known as NormalDistribution.

- Standard deviation first find out what the mean, and then takes each score and figures out how far it is from the mean.
* The more spread out a score is from the central mean, the greater the standard deviation, vice versa
