Question

The graph to the right shows the braking distances for different cars measured under the same conditions. Describe the ways in which this graph might be deceptive. How much greater is the braking distance of Car Athan the braking distance of Car C? Draw the graph in a way that depicts the data more fairly In what way might the graph be deceptive? O A. ere are errors in the graph O B. The units in the graph are not consistent throughout O C. By starting the horizontal axis at 100, the graph cuts off portions of the bars. O D. The graph compares more than two values. Car Car B Car 100 120 140 160 180 200 Braking distance (feet)

Explanation / Answer

a)Answer is (C)

graph is deceptive by starting the horizontal axis at 100,the graph cutoffs portions of the bars.

b)According to graph distance of C is approximately 140 and braking distance of A is about 200

(A-C)*100/C = (200-140)*100/140 = 42%

so Answer is (D) i.e the braking distance of A is about 40% greater than the braking distance of Car C

c)Answer (B)

becuase B start horizontal axis from 0 and it shows the values same as in the original graph
