EDUC 812 the dependent variable anxiety scores. The researcher rejected failed to reject the null hypothesis at the 95% confidence level where t(00) = 00.00, p = .00. Eta square equaled (112 = .000). The effect size was extremely large/ very large/ large/ medium/ small. Eta square was calculated using the formula 112 = tz/(t2 + df). There was/was not a statistical difference between the anxiety scores of male (M = 00.00, SD = 00.00) and female (M = 00.00, SD = 00.00) high school teachers.
