Question
According to Milton Rokeach, there is a positive correlation between dogmatism and anxiety. Dogmatism is defined as a rigidity of attitude that produces a closed belief system (or a closed mind) and a general attitude of intolerance. In the following study, dogmatism was measured on the basis of the Rokeach D Scale (Rokeach, 1960), and anxiety is here measured on the 30-item Welch Anxiety Scale, an adaptation taken from the MMPI (Welch, 1952). A random sample of 30 undergraduate students from a large western university was selected and given both the D Scale and the Welch Anxiety test. The results were as follows:
Subject D Scale Anxiety Test
1 180 60
2 174 64
3 150 45
4 222 102

N 30 30
the correlation coefficient between Dogmatism and Anxiety is rxy= 0.659
1. Null hypotheis H0: row = 0
alternative hypothesis H1: row not= 0 (two-tailed test)
test statistic (t) = r * Sqrt(n-2)/Sqrt(1-r2) follwos t disstibution with n-2 degrees of freedom
= 0.659*Sqrt(30-2)/Sqrt(1-0.6592) = 3.49/0.7521 = 4.64
from t- tables the critical value of t at 5% level with n-2 = 30-2 = 28 degrees of freedom is 2.048
therefore calculated value is > table value(4.64>2.048)
therefore H0 is rejected i.e we may conclude that there is significant correlation between dogmatism and anxiety
