It is a good idea to study experimental subjects in their natural environment because they respond to the test as they would under normal conditions (Option A).
- A good experiment usually has into account all the variables that can affect the variable to be measured (i.e., the dependent variable).
- Thus, it is more suitable to test a hypothesis (either reject or confirm) only when having into account all variables that might affect the experimental group in normal conditions.
- A good experiment also uses a control group in order to make comparisons with the experimental group.
- A control group is defined as an experimental group consisting of subjects/individuals who do not receive the experimental treatment.
In conclusion, it is a good idea to study experimental subjects in their natural environment because they respond to the test as they would under normal conditions (Option A).
