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 ...

Grading on a curve isn't just for college papers--many companies use numeric performance reviews and then fit employees to a bell curve. Unlike school, however, an employee's rating can determine ...

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 ...

What Is A Probability Density Function? A probability density function, also known as a bell curve, is a fundamental statistics concept, that describes the likelihood of a continuous random variable ...

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 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 ...
