The ability to effectively communicate experimental results with others is critical to scientists. The public must be able to understand and follow the logic that leads to the conclusions of an experimenter, while fellow scientists must be able to replicate their experiments. Presenting data graphically allows the reader to view a considerable amount of data quickly and requires little mathematical expertise. The graphs included with experimental results are especially important when communicating with the public, as members of the general public may be less mathematically literate as members of the scientific community. This activity reviews the ingredients of a well-constructed scientific graph.
