Introduction to Measures of Variability

Measures of variability describe how spread out data values are. While measures of center tell us the "typical" value, variability tells us how much the data varies.

The range and interquartile range (IQR) are two important measures that help us understand the spread of data and compare the consistency of different populations.

Understanding variability is crucial for comparing populations and making informed decisions about which group is more consistent or predictable.
