Describe how the range of a distribution is defined and calculated. Choose the correct answer below. A. The range of a data set divides the lowett fourth of a data set from the upper three-fourths. B. The range of a data set is the difference between its median and most extreme value. C. The range of a data set divides the lowest three-fourths of a data set from the upper fourth. D. The range of a data set is the difference between its highest and lowest data values.

The range of a distribution is a straightforward and practical measure that highlights how spread out the data is. It's calculated by taking the highest value in the dataset, subtracting the lowest value, and voila! You have the range. For example, if your highest score is 90 and your lowest is 50, the range would be 90 - 50 = 40. In real-world applications, the range can help you understand variability in any field, from finance to sports. For instance, if you're tracking customer spending, a large range might indicate big spenders and budget-conscious buyers. This insight helps businesses tailor their strategies to meet diverse customer needs and optimize product offerings accordingly!
