C. A pictograph might be more appropriate when comparing data over time where treating the data as part of a whole is not appropriate. D. A pictograph might be more appropriate when the data is categorical.

It looks like you're evaluating statements C and D regarding the appropriateness of using pictographs for different types of data visualization. Let's examine each statement: --- **C.** *A pictograph might be more appropriate when comparing data over time where treating the data as part of a whole is not appropriate.* **Analysis:** - **Pictograph Use:** Pictographs represent data using icons or images, making them visually engaging. They are typically best suited for displaying simple quantities or categorical data. - **Comparing Data Over Time:** When comparing data over time, especially to show trends, line graphs or bar charts are generally more effective. These types of charts can clearly depict increases, decreases, and patterns over sequential periods. - **Treating Data as Part of a Whole:** If the intention is **not** to treat data as part of a whole, a pictograph can sometimes suffice, but it might not clearly convey trends or changes over time as effectively as other chart types. **Conclusion:** While a pictograph can be used to compare data over time without necessarily treating it as part of a whole, it's not typically the most effective choice for this purpose. Other visualization tools like line graphs or bar charts are usually more appropriate for temporal comparisons. --- **D.** *A pictograph might be more appropriate when the data is categorical.* **Analysis:** - **Categorical Data:** This type of data represents categories or groups (e.g., types of fruits, colors, brands). - **Pictograph Use:** Pictographs excel at displaying categorical data because each category can be represented by distinct icons or images, making it easy to differentiate between them visually. **Conclusion:** This statement is accurate. Pictographs are well-suited for representing categorical data, as they provide a clear and visually appealing way to distinguish between different categories. --- **Summary:** - **Statement C:** Partially accurate but not the most appropriate use of pictographs. Other chart types are generally better for comparing data over time. - **Statement D:** Accurate. Pictographs are suitable for representing categorical data.
