Gaussian curves, normal curves and bell curves are synonymous. Each represents how statistical data with normal distribution plots on a graph. Normal distribution describes a particular way ...

The normal distribution is used because the weighted average return (the product of the weight of a security in a portfolio and its rate of return) is more accurate in describing the actual ...

Instead, I'm going to take a different approach here. I'm going to wave my arms a lot, and give you enough examples to convince you that the normal distribution is not only correct, but is inevitable.

Measurements are frequently recorded without their algebraic sign. As a consequence, the underlying distribution of measurements is replaced by a distribution of absolute measurements. When the ...

Folded normal distribution arises when we try to find out the distribution of absolute values of a function of a normal variable. The properties and uses of univariate and bivariate folded normal ...
