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 ...

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 statistics ...

This column is the fourth in a series on parameter estimation, leading up to the justly famous Kalman filter. The discipline is based on the fact that our knowledge of the state of any real-world ...

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 ...
