Reliability testing

1st method
k/k – 1	1.011235955	Sum_Variance	53.52173913
Variance_Total	885.1748792	Cronbach's alpha = (k/k − 1) (1 − sum variance/ variance total)	0.950091984
2nd method (ANOVA TABLE)
Cronbach’s alpha = 1 − (mean square error/mean square rows)			0.952168534
Interpretation: excellent data consistency
