Quizplus · Accepted Answer

A scatterplot would be the best choice to show the relationship between two quantitative variables (parent height and child height) and determine if there is a correlation between them. A pie chart shows proportions of a whole, a stem-and-leaf graph shows distribution of a single variable, and a time-series plot shows changes over time.
