Correct Answer

✅ Option b — The difference between the highest and lowest values in the data set

All Options:

  • AThe difference between the mean and median of the data set
  • BThe difference between the highest and lowest values in the data set
  • CThe number of data points in the data set
  • DThe standard deviation of the data set

Detailed Solution & Explanation

By definition, the range is the simplest measure of dispersion and is calculated as the mathematical difference between the highest (maximum) value and the lowest (minimum) value in a given dataset. Mathematically: Range=Maximum Value−Minimum Value\text{Range} = \text{Maximum Value} - \text{Minimum Value} Hence, **Option B** is the correct answer.
