What will be an ideal response?
The gold standard experimental study in medicine for determining causal relationships is called a randomized controlled trial because participants are randomly assigned to groups and then the group that receives the intervention being tested (e.g., exercise) is compared to control groups. A randomized controlled trial has high internal validity because it is good at discerning causal relationships.
