Final answer:
Two graphical representations that can be used instead of a histogram are bar charts, which show categorical data comparisons, and scatter plots, which display relationships between two quantitative variables.
Step-by-step explanation:
The question asks for two alternative graphical representations to use instead of a histogram. Two alternatives to histograms are bar charts and scatter plots. A bar chart is similar to a histogram but is used to represent categorical data, with the height of each bar indicating the value for each category. A scatter plot, on the other hand, is useful for showing the relationship between two quantitative variables by displaying points at the intersection of their values on a two-dimensional plane.
When deciding which graph to use, consider the type of data and the information you wish to convey. A bar chart is particularly effective for comparing discrete data across categories. A scatter plot is preferred when examining the correlation between two quantitative variables. Since pie charts also represent parts of a whole, they can be a substitute for histograms when displaying distribution among categorical data, but they become difficult to interpret if there are too many slices.
