Given the following question:
Identify the classes and their frequencies
Using the histogram we can find....

It wouldn't be option A because you can see the length of the bar is 60 - 70, - 80 - 90 etc...
The answer would be the third option where it gives a accurate descprition of the 7th graders IQ scores where it's rounded to the nearest whole number.
