Question

In the data set below, what is the range? 9, 4, 9, 2, 8, 2, 1

Answer 1

First put these in order from least to greatest.

1,2,2,4,8,9,9 is the correct order
Range is when we subtract the greatest value of our data set from the smallest so in our case it would be 9-1 which leaves us with our answer that 8 is your range.
