How do you calculate the range of a data set?

• A. Range = maximum value + minimum value
• B. Range = maximum value - minimum value
• C. Range = median value - minimum value
• D. Range = maximum value + median value

Answer: (B)

To calculate the range of a data set, you need to determine the difference between the maximum value and the minimum value. This is done by subtracting the smallest number in the set from the largest number. The formula for range is expressed as: Range = maximum value - minimum value This calculation provides a straightforward measure of the spread of the values within the data set, indicating how far apart the highest and lowest values are. Understanding the range is essential because it gives insights into the variability of the data and helps assess the overall distribution. The other options provide incorrect methods for calculating the range. Options that involve addition or the median do not appropriately capture the difference in value that defines the range. Thus, using the correct formula ensures accurate interpretation of the data set in question.
