Definitions:

IQR

The Interquartile Range (IQR) is a measure of statistical dispersion, being equal to the difference between the 75th and 25th percentiles of a data set.

Chebyshev's Theorem

A statistical theorem stating that for any real dataset, the proportion of values that fall within k standard deviations from the mean is at least 1-1/k^2 for k > 1.

Empirical Rule

A statistical principle that asserts in a normal distribution, almost all of the data is contained within three standard deviations from the mean.

Standard Deviations

Standard deviations are a measure of the amount of variation or dispersion in a set of values, indicating how much the values in a dataset deviate from the mean on average.
