Question

According to a recent study, women have an average (mean) height of 55 in or 140 cm, and men have an average (mean) height of 69 in or 175 cm These averages are shown in the graph to the right. Does the graph depict the data fairly? Choose the correct answer below. A. Yes, because the data are represented in both standard and metric units. B. No, because the heights are one-dimensional measurements, but the graph uses objects of area. C. No, because the graph contains errors D. Yes because the heights are two-dimensional measurements, it is appropriate to depict the data with objects of area.

Explanation / Answer

Heights are one-dimensional measurements but the graph uses objects of area. So this graph is not correct way to represent heights. In case of bar-diagram bar-width should be same and heights are differenet based on the values.

Hence, Option(B) is the correct choice. (Ans).
