A p value of less than .05 was required for significance. The ANOVA was significant F(1, 51)= 5.36, p= 0.25. This result allowed to rejecting the null hypothesis H
0. The effect size was strong (η2= .28), with safety and security factor accounting for 28% of variance of human development.

The results indicated that countries with high safety and security score had significantly higher human development score than countries with low safety and security score. Table 2 shows the mean of the two groups.
