Abstract

This dataset example introduces researchers to two-way Analysis of Variance (ANOVA). Two-way ANOVA is an extension of one-way ANOVA that allows researchers to examine the influence of two different categorical variables on one continuous variable. Two-way ANOVA lets researchers assess the main effect of each categorical variable on the continuous variable in question as well as the interactive effect of the two categorical variables combined. This example uses a subset of data from the 2015 Fuel Consumption Report from Natural Resources Canada to examine whether an automobile’s city fuel consumption differs across types of automobile fuel as well as across types of transmission. This allows for comparisons of city fuel consumption across both variables. The sample dataset has been cleaned and organized to make this ...
