Answer to Question 1

ANS: A, B, D, E
Limitations are restrictions or problems in a study that may decrease the generalizability of the findings. All studies have limitations, and these might be theoretical and/or methodological in nature. Theoretical limitations are weaknesses in a study framework and conceptual and operational definitions of variables that restrict the abstract generalization of the findings. Methodological limitations are factors in the study design that can limit the credibility of the findings and restrict the population to which the findings can be generalized. Studies can be generalized to the population from which the sample was drawn; a sample drawn from one geographic area can, in general, be generalized back only to that area. The findings from a study conducted in Afghanistan (and published in English in a British journal) can be generalized back to Afghanistan. Studies conducted in one language and published in another may be flawed in other ways.

Answer to Question 2

ANS: A, B, C, D, F
Interpretation includes several intellectual activities, such as examining evidence, forming conclusions, identifying study limitations, generalizing the findings, considering implications, and suggesting further research. Generalizations should be specific to the population from which the sample was drawn, and should be based on the total contribution of research, to date. Excuses should not be made.
