Definitions:

Chebysheff's Theorem

A statistical theorem that provides a minimum probability for how much data falls within a certain number of standard deviations from the mean, applicable for any data distribution.

Standard Deviations

A measure of the amount of variation or dispersion of a set of values, indicating how much the values differ from the mean of the set.

Variance

Variance measures the dispersion of a set of data points around their mean value, indicating how spread out the data is.

Standard Deviation

A statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.
