Document Summary

A response variable measures an outcome of a study o. An explanatory variable may explain or influence changes in a response variable o. The idea behind this language is that the response variable depends on the explanatory variable. In many studies, the goal is to show that changes in one or more explanatory variables actually cause changes in a response variable: other explanatory-response relationships do not involve direction causation. The most useful graph for displaying the relationship between two quantitative variables measured on the same variables is a scatterplot. The values of one variable appear on the horizontal axis, and the values of the other variable appear on the vertical axis. Each individual in the data appears as a point in the plot fixed by the values of both variables for that individual. Always plot the explanatory variable on the horizontal axis o o. Call the explanatory variable x, and the response variable y.
