How can students best display voting data from an apple sampling activity?

A bar graph is the most suitable choice for displaying voting data from an apple sampling activity because it effectively represents categorical data, which is what the voting results would likely consist of. Each category can represent a different type or variety of apple that students tasted and voted on.

In a bar graph, the length of each bar corresponds to the number of votes received for each apple type, allowing for an easy visual comparison between categories. This format is particularly good for highlighting differences in preferences, making it straightforward for students to interpret the data at a glance.

While other types of graphs, such as pie charts, could also be used to show proportions of votes, they don't allow for as clear a comparison between different categories as bar graphs do. Line graphs and scatter plots are best used for showing trends over time or relationships between two variables, which isn't the goal in this scenario of displaying voting preferences.
