Explanation
Question 1. Use the first graph. Find the line that is the straightest across the four groups, thus, the line with the smallest range. Notice that the Reference line shows about 100, 120, 90, and 80 for the four groups. These numbers are more similar than any other category. For example, the numbers for Large Print are approximately 20, 90, 10, and 140. The range for Large Print (140 – 10 = 130) is much greater than the range for Reference (120 – 80 = 40).
The answer is choice (D).
Question 2. Use the second graph. The section of the Used Adult bar for Science/Nature (grey portion) starts at approximately 80 and ends at approximately 150. So, the number of Science/Nature books is approximately 150 – 80 = 70, choice (A).
Question 3. Use the first chart. There were approximately 220 New Adult (A) audio books, 330 New Children’s (B) audio books, 50 Used Adult (C), and 200 Used Children’s (D) audio books. Putting these in order from greatest to least gives you: (B) 330, (A) 220, (D) 200, (C) 50, choice (B).
