A t-statistic was also measured for Table5.2 to test the hypothesis and with
the r coecient 0.806, t yielded 7.205 with the given degree of freedom of n – 2 =
28; given α = 0.01, the critical value of t was 2.7633. Since the t-statistic of 7.205
> 2.7633, this clearly rejected the null hypothesis (H
0
) and the alternate (H
1
) was
accepted.
Table5.3 illustrates a higher positive correlation between Sem Rank and HCR
Rank. It shows a signicant positive correlation between scores (r = 0.919 or 91.9%).
e asterisks indicate signicant correlation at 0.01, level (two-tailed). e signi
