Standard Deviation

The square root of the variance, measuring the dispersion of a dataset relative to its mean.

Mean

The mathematical calculation where you add all the numbers in a set and divide by the number of elements to find the average.

Mound-Shaped Distribution

A data distribution that is symmetric and bell-shaped, often resembling the normal distribution but not necessarily having its mathematical properties.
