How is the "range" of a data set calculated?

• A. Maximum value + Minimum value
• B. Maximum value - Minimum value
• C. Average of all values in the set
• D. Sum of all values divided by the count

Answer: (B)

The range of a data set is calculated by finding the difference between the maximum value and the minimum value in that set. This measurement provides insight into the spread or dispersion of the data points. By subtracting the minimum value from the maximum value, you obtain a single number that reflects how far apart the largest and smallest values are from one another. This concept is critical in statistics, as it helps to understand the variability within the dataset—how much the values differ from one another. A larger range indicates a wider spread of values, while a smaller range indicates that the values are more clustered together. Thus, by selecting the correct calculation of maximum value minus minimum value, one accurately determines the range, offering valuable information about the data set's distribution.
