Chantelle is interested in studying the effects of energy drinks on college student alertness. If she wants to test whether the consumption of energy drinks increases student alertness, the best research method is .

A) Survey research

B) Naturalistic observation

C) Correlational research

D) Experimental research

The correct answer to this question is D) Experimental research

Explanation:

Experiment research allows researchers such as Chantelle to test the effect of a substance, medicine, etc. because in this research design half of the participants will receive the "special treatment", in this case, the drink; while half will not receive it or will receive a placebo (substance with no effect). In this way, if the substance or treatment has an effect on participants the research will know this by comparing those with the treatment (experimental group) and those without it (control group). This is ideal for Chantelle because in this way she will clearly know if the drink increases or decreases students' alertness.
