Question

Jonathon wanted to know how far people could swim in 30 minutes. He collected data from 10 people about how many miles they could swim

in 30 minutes and obtained the following results:
0.25 0.80 0.75 0.93 0.24 0.50 0.75 0.98 0.35 0.85
What is the range of the data Jonathon collected?
A. 0.60
B. 0.64
C. 0.74
D. 0.75

Answer 1

A. 0.60
Add them all up then divid by the total number of results. So 6.1/10 =0.60

Answer 2

0.74

Explanation:

To find the range of a data set, subtract the largest number form the smallest number.

So, first, order them.

Then find the largest and the smallest value.

Subtract them like you would subtact any number, so it would look like this:

0.98-0.24=0.74
