Smith Introduction For most of us, we heard the phrase meta-analysis reasonably early on in our academic career, probably in one of the first few lessons of our Introduction to Psychology course.
And he said this in before the internet was even around and the whole world of research opened up! With all of this information available, we need to be able to pull everything together to move forward or we risk missing important findings from research already done.
As this research project is a meta-analysis, Dr. Redmond asked if I could write a quick summarization of what a meta-analysis is, what it entails, and some problems we may encounter while doing this analysis.
So how do we conduct a meta-analysis? The first step is defining what the question is followed defining what to include in the study, which is the second step. The second step may be the most important as it not only helps to clarify what you should be looking for and therefore save time when looking for and gathering databut also allows for a more precise research report which can have a greater impact on the field.
The third, and most obvious, step is to take your definitions and collect the data and assemble a bibliography from which to work perform an analysis. You then need to code the data and perform statistical analyses fourth step in order to see what that data means.
Once you have performed the statistical analysis you need to summarize the findings fifth step.
After all of this, the sixth and final step is to make this information public for others to use. Rathe,Bulletin of the Medical Library Association, 83, p.
Potential Problems While this may seem straight forward, Arendt describes a few things to keep in mind and problems that we may encounter when conducting a meta-analysis Arendt, The first is that the search for articles needs to be as through and well-defined as possible.
This should be common sense, but it can often lead to problems. This not only entails doing a thorough search of the databases that are the most common, but also looking outside of these areas.
One example that Arendt uses is that our searches tend to be for English articles, which could prevent us from conducting a thorough search. The first of these problems has to do with the combination and comparison of what may not be considered comparable variables.
A meta-analysis is only as good as the studies included in the analysis. Works Cited Arendt, J. Behavioral and Social Sciences Librarian 26 1 Personnel Psychology 65 2 Primary, Secondary, and Meta-Analysis of Research.
