%X Computer programs were used to construct overall population and simulated experimental procedures were applied to conduct sampled studies in order to probe into the differences between the methods of significance t testing and meta analysis in testing the data of an experimental result and its practical application. The simulated experimental results showed that significance t testing is highly related to population distribution effect size and sample capacities, yet rarely related to the numbers of randomly selected samples; mean value of the selected samples effect size can be used as an estimated value of population effect size, and it is closely related to sample capacities and numbers of selected samples; the data result of practical application provided in this study can be used as a basic reference for researchers who are engaged in an experimental study of meta analysis method.
