A pearson correlation was conducted to test the relationship between Age (Mdn = 35.80) and Education (Mdn = 14.03).

There was a statistically significant relationship between the two variables, \(\rho = .52, p < .001\).The relationship was positive and strong.

As the independent variable increased, the dependent variable increased.
