Nonresistant Measures

Definition

Nonresistant measures are statistical measures that can be greatly influenced by extreme values or outliers in a dataset. They may not accurately represent the central tendency or spread of the data.

Analogy

Imagine nonresistant measures as delicate glass sculptures that easily break when exposed to strong forces. Just like these sculptures, nonresistant measures can be easily distorted by extreme values.

Mean: The mean is a nonresistant measure calculated by summing all values in a dataset and dividing it by the total number of observations.

Range: Range is a nonresistant measure representing the difference between the maximum and minimum values in a dataset.

Standard Deviation: Standard deviation is a nonresistant measure that quantifies how much variation or dispersion exists within a dataset based on its average distance from the mean.
