%X A sampled study through computer constructed population subject group and simulated experimental study procedures probed into the difference between significance t-test and meta-analysis in testing data rusults of experiments. In the process of simulated experiment, the t-test result was affected by significance level, sample capacity and population effect size. Thus reliability of statistical inferences was affected. Suggestions: In the process of significance test, statistical testing power should be estimated; inferring population subject group througlt samples as factors, meta-analysis has high accuracy and reliability, it will very likely be a very important statistical method in later research in psychological science.
