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. what is an advantage of using the range as a measure of variation? a. it uses only two entries from the data set. b. it uses all entries from the data set. c. it is easy to compute. what is a disadvantage of using the range as a measure of variation? a. it uses all entries from the data set. b. it is hard to compute. c. it uses only two entries from the data set.

Explanation:

The range of a data - set is defined as the difference between the maximum and minimum values. This makes it easy to calculate as it only involves identifying two values. However, since it only uses the maximum and minimum, it doesn't take into account the distribution of all the other data points in the set.

Answer:

1. D. The range is found by subtracting the minimum data entry from the maximum data entry.
2. C. It is easy to compute.
3. C. It uses only two entries from the data set.
