A bar graph is most effective for displaying data on how many times students used a pencil because it allows for clear and easy comparison of discrete categories, such as different students or different time periods. Each bar represents a specific count of pencil usage, making it straightforward to see differences in usage frequency among the categories at a glance.

Additionally, bar graphs are particularly useful when dealing with categorical data or when the data involves counts, as is the case here. The length or height of each bar proportionally represents the number of times a pencil was used, enabling a simple visual interpretation of the data.

Other types of graphs, while useful for different data presentation tasks, would not serve this particular dataset as effectively. For instance, a pie chart is better suited for displaying proportions of a whole, a line graph is ideal for showing trends over time, and a scatter plot is typically used for showing relationships between two continuous variables rather than counting occurrences.
