A bell curve is a graph used to visualize the distribution of a set of chosen values across a specified group that tend to have central, normal values that peak, with low and high extremes tapering ...

The normal distribution is pretty cool. It’s a mathematically determined probability distribution that does a good job of describing the patterns of variability between scores for many variables in ...

It's a long-held assumption that human performance fits a normal (or Gaussian) distribution — a bell curve in which only a very small number of people are outliers. Consequently human resource ...

The bell curve, that beautiful form of regularity, is getting turned upside down. In the mid-19th century, a few of Europe's finest scientists and mathematicians noticed something peculiar about the ...

The normal distribution is a concept in statistics that assumes all values are distributed in the same pattern. It requires symmetry and consistent proportions in the distribution of values. Normal ...

One criticism of the normal distribution is that it is over-applied and over-used. This criticism is partly based on the ideas that (a) fewer naturally occurring variables than one might believe ...
