A reviewer evaluates a manuscript in which the authors used a bar graph to display the relationship between participants' age (a quantitative variable spanning a wide range of values) and their memory scores. The reviewer correctly argues that a(n) _____ should have been used instead, because it plots each individual's scores as a single point at the intersection of the two axes and preserves the full distribution of values rather than collapsing them into group means.
