Range and Interquartile Range

Question 1 • HCISD-Mathematical Models with Applications B-CR SUMMER

What steps should be used to find the range of a set of data?

Answer
A
Put the values in order, then locate the value that is far away from every other value.
B
Subtract the maximum and minimum values.
C
Add all of the values together, then divide the sum by the number of values.
D
Add the two middle values together, then divide the sum by two.

Explanation

To find the range, subtract the smallest value from the largest value: range = maximum − minimum. Therefore, the correct choice is “Subtract the maximum and minimum values.” Choice A describes looking for an outlier, C describes finding the mean, and D describes finding the median for an even-sized data set.
