Gas chromatography (GC) is a method of separating mixed compounds.
The separation will depend on each compound's retention time. Compounds with
higher molecular weights will elute out slower than those with lower molecular
weight. This is due to their difference in boiling points. The larger the
structure, the higher the boiling point.

Explanation:
At the beginning of your study, you need your two groups to be as statistically similar as is humanly possible. That way, when you control for other variables, you can reasonably attribute any statistically significant differences at the end of the study to your intervention.
