average monthly electric cost\nhow could the graph be redrawn so that the difference in monthly electric cost does not appear as great?\nthe scale on the y - axis could be changed to 0 - 150.\nthe scale on the y - axis could be changed to 100 - 120.\nthe interval on the y - axis could be changed to count by 1s.\nthe interval on the y - axis could be changed to count by 20s.
Answer
Explanation:
Step1: Understand graph - scale effect
The appearance of differences in a bar - graph depends on the y - axis scale and interval. A smaller scale range and larger interval make differences seem more pronounced.
Step2: Analyze option A
If the y - axis scale is changed to 0 - 150, the range is large. This will compress the bars vertically and make the differences between the average monthly electric costs of the companies appear smaller.
Step3: Analyze option B
Changing the scale to 100 - 120 will make the differences seem even more pronounced as the range is very small.
Step4: Analyze option C
Changing the interval to count by 1s will make the graph more detailed but will not reduce the visual difference in the bar heights.
Step5: Analyze option D
Changing the interval to count by 20s will make the graph less detailed but will not necessarily reduce the visual difference in the bar heights as effectively as changing the scale to 0 - 150.
Answer:
The scale on the y - axis could be changed to 0 - 150.
