Critique guidelines

Summary part

1. Justification/Motivation for research.  Explain any theory specific terminology.

2. Some sample characteristics (give a sense of what the population is to which the data will be generalized)

3. Conceptual model(s) tested.  For example "For this analysis, the DV was Y and the predictors were X1, X2 and X3"

4. The actual analysis used.

5. General results.  What did they find?

Critique

The critique is more open and actually take place in the summary part as well if you e.g. thought their theoretical reasoning was off, sample was uncharacteristic etc.  Regarding results, the following are the sorts of things you want to look for though this is not an exhaustive list by any stretch: reliability of measures in their sample, confidence intervals, effect sizes, graphics (clear), tests of assumptions and how violations were dealt with, outlier details, how they dealt with missing values if any, etc.

Conclusion: Do you buy what they're selling?  How much weight do you give the study?
