A biologist records counts of different fish species caught in a lake. If the results are organized in a frequency distribution graph, what kind of graph should be used?

When you’re displaying frequency data for distinct categories, use a bar graph. Each category (here, a fish species) gets its own bar, and the height shows how many were caught, making it easy to compare how common each species is. A histogram is for continuous data that are grouped into intervals, so it would imply a numerical spectrum rather than separate species. A polygon (frequency polygon) connects points from a histogram, which again suits continuous data, not categorical counts. So the bar graph is the best choice for showing the distribution of counts across different species.
