Michael W. Marek

There are two kinds of meta-analysis. Most common is qualitative analysis, in which the data of multiple studies are aggregated and analyzed.

But qualitative meta-analysis is also possible, where you look for themes in the findings and lessons learned of multiple studies.

This paper, for example, used qualitative meta-analysis:

Pierre Bush

Thank you Felipe and Michael.

Michael: I got that: two types of Meta-analysis: quantitative, and qualitative.

Thank you for the example you shared.

Mahdi Inaayah Kareem al-Utbi

Dear Pierre

You have done it. Yours is the best method to carry out a meta-analysis. It is within the aims and purposes of your study that you might decide to make it quantative or qualitative.

Regards

Hello Mahdi,

That's correct. Can it be a mix study though? Both qualitative and quantitative? I know that mix studies are very challenging, but in my project, I have identified some qualitative studies and quantitative ones. I might exclude the qualitative ones down the road.

Of course, it can be a mix of both. And as I see it, whenever quantitivness is there, it would be better to explain it with qualitativeness. So, a mix is the result.

Pierre Bush, I am glad to answer this question; firstly I found it is very difficult to begin meta-analysis at first due to its complexity and in addition, it needs a good team to tackle a big amount of work; but if you are a passionate learner and have a good team you can do it. Please kindly check Cochrane handbook of systematic reviews and related video materials on youtube to understand different facets. Then start to read some published meta analysis focusing on the method section that will be the perfect way of learning in the beginning. Here I have attached some of my published works. I suppose these may help you further.
