How is the range calculated in statistical analysis?

The range in statistical analysis is calculated by subtracting the lowest score from the highest score. This process provides a measure of the spread or dispersion of a data set, indicating how much variation exists between the extreme values. The range is a simple yet effective statistic that helps to understand the overall distribution and variability of the data.

Using the difference between the highest and lowest scores allows analysts to quickly gauge the scope of the data set. In practical applications, knowing the range can help identify potential outliers and assess the data’s variability, which can inform further statistical analysis and decision-making.
