In the context of the internal validity of different study types, what does Figure 6.1 suggest about a well-designed quasi-experiment?
Explanation
The quality of a study's design is paramount. While true experiments are the gold standard for internal validity, a well-controlled quasi-experiment can provide more trustworthy results than a sloppy experiment riddled with confounds.
