There were no significant differences between identified genders on the distributions of age, ethnicity, or education (right column).

*The measure of center used for the age variable was the mean, and for categorical variables of ethnicity/race and education it was the mode. For the education variable, student refers to “some college.”

**Hypothesis testing of significant differences between males and females. Age: two-sample t test adjusted for unequal sample sizes. Ethnicity/race and education: a χ² test of independence.
