Answer
To understand how the response variables change when the independent variables differ, a controlled experiment needs to be conducted. Suppose the independent variable is the amount of hormones injected in a unit, and the response variable will be the weight and height of the unit. After the hormone is injected, the difference in the structure of the subject’s body is observed. Thus, the main objective of conducting experiments is to observe the response variable after the conditions change.
