| Summary: | The present study aimed at clarifying the various shortcomings of the Cohen’s criteria for the interpretation of the values of
the practical significance indicators. The hypothetical data were used for two experimental and control groups and
calculating the paired-samples t-test. To clarify the inadequacy of Cohen’s criteria in interpreting practical significance
indicators, it was compared with another criterion which is Black’s Modified Gain Ratio. Through the compatibility of
mathematical equations to calculate the practical significance and the values of the interpretations of the correlation
coefficient, the present study suggested that a criterion for the practical significance should be as follows: small when the
values of the index (d) are less than (0.631), medium when the values are between 0.631 and 1.50 and large when the values
are equal to or greater than (1.51). The study showed the justifications that distinguish this criterion from the Cohen
criterion. |
