Several statistical measures are used to quantify variability: 1. Standard Deviation: Indicates the degree of dispersion from the mean. 2. Variance: The square of the standard deviation, providing a measure of the spread. 3. Interquartile Range (IQR): Measures the spread of the middle 50% of the data. 4. Coefficient of Variation (CV): The ratio of the standard deviation to the mean, useful for comparing variability between datasets with different units or means.
