What are some good things to look for when evaluating a psychology method, design and statistics?

Contextual point: I am trying to revise for an exam in two days and one of the questions asks us to write an evaluative summary of the methods and statistics from the abstract and results section.

I have some notes on how to achieve this, but I was wondering if people have any pointers on what to look out for.

Some of the things I already have include the basics such as looking at sample size, effect size, evaluating the choice of design (ie experimental or quasi-natural) etc.

Thanks for the help (if I get any). If I get an A on this exam I will make love to you (or bake you cookies).
