A meta-analysis would be the best procedure in this scenario because it combines the results of many small studies to provide a more accurate estimate of the true effect size. This approach would increase the statistical power, reduce random errors, and allow for more comprehensive conclusions as it provides a more substantial statistical basis for further studies. A correlation coefficient would only be suitable when analysing relationships between two variables, and a survey would be inadequate for estimating the size of the results. A statement of parsimony is not a statistical procedure, but rather a principle used in scientific explanations.
