Based on the Mega stat printout, the correlation coefficient between education level and social activity is 0.61 which is a strong positive correlation. When tested at the 0.01 level of significance, the p-value is less than 0.01, which means that we can reject the null hypothesis that there is no correlation between education level and social activity. Therefore, we can conclude that social activity and education level are related, with increased levels of education resulting in increased social activity.
