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 adding the first and last data entries. b. the range is found by subtracting the first data entry from the last data entry. c. the range is found by subtracting the minimum data entry from the maximum data entry. d. the range is found by adding the minimum and maximum data entries.

Explanation:

The range of a data - set is a measure of variation. It gives an idea of how spread out the data is. To find it, we look at the difference between the largest and smallest values in the data set. An advantage of the range is that it is easy to calculate. A disadvantage is that it is highly affected by outliers (extreme values), as it only depends on the minimum and maximum values and ignores the distribution of the other data points. For the multiple - choice question, the correct way to find the range is by subtracting the minimum data entry from the maximum data entry.

Answer:

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