Which of these would NOT be an appropriate use of a pictograph?

A pictograph is a visual representation that uses pictures or symbols to convey information and data visually. It is best suited for comparing quantities or data sets in an easily interpretable format.

The choice indicating the comparison of a bunch of friends' top five favorite kinds of pizza would not be appropriate for a pictograph because this scenario involves qualitative data rather than quantitative data. A pictograph is meant to illustrate how many of something exists, making it ideal for numerical comparisons. When discussing favorite kinds of pizza, the data being conveyed is categorical, which is better represented through bar graphs or tables that can display the frequency of preferences without suggesting an exact quantity.

In contrast, the other scenarios listed involve quantitative data that lend themselves well to pictographs, making them suitable for visually and effectively communicating the amount of pizza eaten, sodas consumed, or films watched among various groups. These scenarios provide clear numerical values that could be represented by pictures for easy comparison.
