I returned home late last night after being on the road for a solid 7 days, and I am off to a breakfast meeting this morning.  So, I am using an old classic quote from Dr. Robert Marzano.  This was pulled from a blog cast Bob did four years ago, and shows us how the mind of a great educational researcher works.  No additional explanation is required.

 Meta analysis is just a fancy way of saying quantitative synthesis.

Thanks Bob.  I got it now.
