What does the range in a data set refer to?

The range of a data set specifically refers to the difference between the highest and lowest scores. This is calculated by subtracting the minimum value from the maximum value in the set, providing a measure of how spread out the values are. By focusing on these two extreme values, the range gives a quick snapshot of the variability in the data. It's a fundamental concept in statistics that helps in assessing the dispersion of the data without being influenced by other factors or outliers.
