A bell curve is a graph depicting the normal distribution, which has a shape reminiscent of a bell. The top of the curve shows the mean, mode, and median of the data collected.

While the curve itself still represents normal distribution, the statistical outcomes outside of the norm are actually higher, called “excess kurtosis.” Another limitation of bell curves is the ...

Despite the importance of data assumptions, many studies fail to report tests for normality. As a result, it’s unclear how many findings in finance and accounting research rest on shaky statistical ...

The concept of the normal curve, also known as the Gaussian distribution or bell curve, is foundational in understanding how data is distributed in many natural phenomena. It's a pattern that ...

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 ...

The normal curve, on the other hand, is a family of symmetric curves based on the normal distribution function. The specific dimensions of each normal curve depend on the value of the mean, and ...

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 ...

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.
