This should be critically regarded when interpreting the outcomes of a meta-analysis.[18][19]
Modern-day statistical meta-analysis does much more than simply Blend the effect measurements of a set of scientific studies employing a weighted average. It might exam In the event the outcomes of experiments present far more variation when compared to the variation that is expected because of the sampling of various quantities of analysis participants. On top of that, study attributes which include measurement instrument made use of, population sampled, or areas of the studies' style and design is often coded and used to reduce variance on the estimator (see statistical products above).
