Language  Test of reference (X_{1}) 30  School Test (X_{2}) 24  P_{1} = 1, P_{2} = 0.8 P_{1} = P_{2} (almost)  /Z/ = 1.42  Since /Z/ < 1.96, Scores of both the Test are consistent and are significant at 5% level of significance. This means that the students are comfortable to recall memory andanswer point wise 
Science  22  13  P_{1} = 0.26, P_{2} = 0.13.This means P_{1} ≠ P_{2}  /Z/ = 2.72  Since /Z/ > 1.96, Scores of both the tests are not consistent and are not significant at 5% level of significance. This means the students are not comfortable with science. This focuses on the fact that 50% students may belong to divergent thinking. 
Math  18  16  P_{1} = 0.73, P_{2} = 0.53 P_{1} = P_{2} (almost)  =1.81  Since /Z/ < 1.96, the scores of both the tests are found consistent. This means that the performances of the students are significant at 5% Level of significance.
