Posted by Tzeni on Wednesday, December 2, 2009 at 1:38pm.

When the conditions of a study resemble or approximate only the conditions of interest, questions may be raised about the ''blank'' of the study.
A external validity
B internal validity
C standardization
D randomization

This question is very difficult for me. I can't find exactly the right answer in my text book. I believe is A but I'm not at all sure.
