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 A than the braking distance of Car C? Draw the graph in a way that depicts the data more fairly.
A bar graph with horizontal axis labeled "Braking distance (feet)" from 100 to 200 in intervals of 20 and vertical axis labeled with three cars contains three horizontal bars of equal height that do not touch each other. From top to bottom, the bars to the right of the vertical axis labels extend over horizontal ranges as follows: "Car A," 100 to 186; "Car B," 100 to 136; "Car C," 100 to 130. All values are approximate.100120140160180200Car ACar BCar C
Braking distance (feet)
In what way might the graph be deceptive?
A.
By starting the horizontal axis at 100, the graph cuts off portions of the bars.
B.
The units in the graph are not consistent throughout.
C.
There are errors in the graph.
D.
The graph compares more than two values.
How much greater is the braking distance of Car A than the braking distance of Car C?
A.
The braking distance of Car A is about 120 ft greater than the braking distance of Car C.
B.
The braking distance of Car A is about the same as the braking distance of Car C.
C.
The braking distance of Car A is about
4040%
greater than the braking distance of Car C.
D.
The braking distance of Car A is more than twice the braking distance of Car C.
Draw the graph in a way that depicts the data more fairly. Choose the correct graph below.
A.
A bar graph with horizontal axis labeled "Braking distance (feet)" from 0 to 200 in intervals of 20 and vertical axis labeled with three cars contains three horizontal bars of equal height that do not touch each other. From top to bottom, the bars to the right of the vertical axis labels extend over horizontal ranges as follows: "Car A," 0 to 186; "Car B," 0 to 136; "Car C," 0 to 130.
