Document Summary

The role-type classification: studies involving two variables. The explanatory variable (independent variable) the variable that claims to explain, predict, or affect the response, x. The response variable (dependent variable) the outcome of the study, y: further classify according to type (categorical or quantitative) Compare the distributions of the quantitative response for each category of the explanatory variable. The relationship between a categorical explanatory variable and a quantitative response variable is summarized using: data display: side-by-side boxplots, numerical summaries: descriptive statistics. Exploring the relationship between a categorical explanatory variable and a quantitative response variable amounts to comparing the distributions of the quantitative response for each category of the explanatory variable. In particular, we look at how the distribution of the response variable differs between the values of the explanatory variable. To summarize the relationship between two categorical variables, we create a display called a two-way table.
