Question

explain how to find the range of a data set. what is an advantage of using the range as a measure of variation? what is a disadvantage? explain how to find the range of a data set. choose the correct answer below. a. the range is found by subtracting the first data entry from the last data entry. b. the range is found by adding the first and last data entries. c. the range is found by adding the minimum and maximum data entries. d. the range is found by subtracting the minimum data entry from the maximum data entry.

Explanation:

To find the range of a data set, we need to determine the difference between the maximum and minimum values. The range is calculated as \( \text{Range} = \text{Maximum value} - \text{Minimum value} \).

• Option A is incorrect because the first and last data entries don't necessarily represent the minimum and maximum (data could be unordered).
• Option B is incorrect as range is not found by adding any entries.
• Option C is incorrect because range is a measure of spread, not a sum of min and max.
• Option D is correct because it describes the process of subtracting the minimum from the maximum, which is the definition of range.

Answer:

D. The range is found by subtracting the minimum data entry from the maximum data entry.
