Answer

a. Pictographs are best when you want a simple, visual way to compare small groups of data, especially for younger audiences or to make data more relatable.
b. Circle graphs (pie charts) are ideal for showing how different parts make up a whole, especially when there are a few categories and you want to highlight proportions.
**c. A stem-and-leaf plot is more informative than a histogram when you need to see individual data values and their exact distribution, especially with smaller data sets. For example, showing test scores with exact values and identifying duplicates is clearer in a stem-and-leaf plot.

Pictographs shine in situations where you want to present qualitative data in a way that’s visually appealing and easy to understand, especially for younger audiences. For example, if you’re showcasing survey results about favorite fruits among kids, where each fruit image represents a certain number of votes, pups, or kitties, this approach can make the information more relatable and fun!
On the other hand, circle graphs, or pie charts, are fantastic for illustrating parts of a whole, especially when you want to emphasize proportion. For instance, if you’re displaying a budget breakdown—like how much of your allowance goes towards snacks, savings, and entertainment—a pie chart gives a clear visual of where most of your money is going, making it easy for viewers to grasp the relative sizes at a glance!
