Methodology
Figure 2 below shows the average age of male and female riders from our July 2017 data set. In order to test for significance, we used the two-tailed independent t-Test. Our independent variable (age) is categorical, and our dependent variable (age) is continuous. Based on this information, we determined that we could use either the t-Test or an ANOVA. Because the ANOVA is more complex, we decided that the simpler t-Test would be more appropriate.
