Mean = (Sum of all data points) / (Number of data points)
Median: The middle value in an ordered data set
Mode: The most frequent value in a data set
Range = Maximum value - Minimum value
Coefficient of Variation = (Standard Deviation / Mean) * 100
Z-Score = (Data point - Mean) / Standard Deviation
