Statistics shows data is often grouped on a bell curve distribution, but a business study reveals that extreme outliers can skew research – with big implications.

Some can have long tails, for example, which actually skew probability. While the curve itself still represents normal distribution, the statistical outcomes outside of the norm are actually higher, ...

Origins of the IQ bell curve meme The discovery of normal distribution is sometimes attributed to French mathematician Abraham de Moivre in 1738, but credit is more often given to the man who ...

Learn how to make a Bell Curve or generate a normal distribution cure in Microsoft Excel with data. This step by step illustrated guide will help you with that.

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 ...

Well, let’s dissect that a bit. Suppose that you are teaching a class on statistics, and your distribution of scores is normal - and the mean (average) score is 80 (of a possible 100).

Income inequality has been growing in the U.S. for decades. One way to look at it, to see how non-normal the distribution of income has become, is to consider a basic concept in statistics.
