Question

If the stars presented to the companies are used to give rating on a scale of 10, then the rating of company C is

• A. Pictograph
• B. $\frac{1}{2}$
• C. $\frac{1}{4}$
• D. 2

Answer 1

The correct option is B $\frac{1}{2}$

The stars presented to company C is $\frac{1}{4}$ star. When it is converted to a rating on 10 scale, $\frac{1}{4}\times 2=\frac{1}{2}$. However, the problem in pictographs is you can not determine the portion of the picture the image represents. For example, in this case, company C has $\frac{1}{4}$ star but the creator might have intended $\frac{1}{3}$ star. This makes pictographs difficult to read and are not preferred.
