What will be an ideal response?
The study of disease rates that vary among different population groups is called epidemiology.
A scientist observes a natural phenomenon and develops a tentative explanation called a hypothesis.
For example, if a scientist suspects caffeine intake affects behavioral changes in children, he may choose to conduct a(n) randomized, double-blind, placebo-controlled study where he randomly assigns children in the study to either a regular, normal-caffeine level diet or a high-caffeine diet group and then studies behavior without knowing which group received which diet.
The children who are in the group that receives a high-caffeine diet constitute the experimental group.
The children who are in the group that receives a regular, normal-caffeine level diet make up the control group.
If the results of many studies and much data support the original explanation about a relationship between caffeine intake and behavior, a theory is formed
