Definitions:

Mean

To determine the arithmetic average, one sums up every number in the collection and divides by the number of elements in the collection.

Standard Deviation

An indicator that measures how much a set of data points spread out or diverge.

Z-Score

An index that quantifies how far a particular value stands from the dataset's mean, measured in units of standard deviations away from the mean.

Z-Scores

A measure that represents the number of standard deviations a data point is from the mean of the dataset.
