Quantitative research synthesis is used in research which concentrates on describing and analyzing phenomen by using numerical data and empirical models. There are some statistical methods that can help synthesists summarize research results. This quantitative procedure is called meta-analysis. Among the techniques there are counting study outcomes, combining probabilities from inference tests, averaging  effect sizes, and examining the variability in effect sizes across studies. Quantitative research synthesis is an extension of the same rules of inference required for rigorous data analysis in primary research. If primary researchers must specify quantitatively the relation of the data to their conclusions, the next users of data should be required to do the same. Before using quantitative synthesis, it is important to take a closer look at some of the unique features off accumulated research results.
