Question

cost per doctor visit
cost per doctor visit ($)
health plan
how might the graph be redrawn to emphasize the difference between the cost per doctor visit for each of the three plans?
the scale on the y - axis could be changed to 0–100
the scale on the y - axis could be changed to 25–40
the interval of the y - axis could be changed to count by 5s
the interval of the y - axis could be changed to count by 20s.

Explanation:

Step1: Analyze current graph

The current y - axis seems to have a large range which makes differences look smaller.

Step2: Consider option A

Changing to 0 - 100 will make differences even less noticeable as the range is too large.

Step3: Consider option B

Changing to 25 - 40 will zoom in on the relevant values, emphasizing differences.

Step4: Consider option C

Counting by 5s doesn't necessarily emphasize differences as much as changing the range.

Step5: Consider option D

Counting by 20s will make the graph less detailed and differences less visible.

Answer:

B. The scale on the y - axis could be changed to 25 - 40
