Question

Find the range and the midrange for the following data set: 7.25, 6.75, 6, 7.5, 7, 7, 7, 7.5, 6, 8.5, 8.5, 6.5, 7, 5.5, 8.5, 7.25, 7.25 a Range = 7.25, Midrange = 6.25 b Range = 3, Midrange = 7 c Range = 5.75, Midrange = 6.5 d Range = 8, Midrange = 7.25

Answer 1

B

Explanation:

The min and max numbers are 5.5 and 8.5. To find range, you subtract the bigger number by the smaller number. To find midrange, you find the median of the 2 min and max numbers.

8.5-5.5=3

5.5 6 6.5 7 7.5 8 8.5

1 2 3 4 5 6 7

So the range is 3 and the midrange is 7.
