What one advantage of doing a field experiment instead of a laboratory experiment?

A. There are no variables when you do a field experiment.

B. It is easier to control variables in a field experiment.

C. Field experiments do not require any measurements.

D. Field experiments are better at representing what happens in the real world.

Answer with Explanation:

Field Experiment: While performing field experiment, there is a Independent Variable and a Dependent Variable. For example

y=f (x), where x is Independent Variable and y is Dependent Variable.

There are some Extraneous variables which affect the field experiment

1. Location or Place at which it is being performed

2. Temperature

3. Pressure

Outcomes may Vary, it is not Fixed.

For Example: Value of acceleration due to gravity may vary at different places on earth.

Laboratory experiment:

While doing laboratory experiment, it is performed under Fixed room temperature, and Pressure. Outcomes of this kind of Experiment are fixed.

For Example: Calculation of Acceleration due to gravity using Simple Pendulum

⇒So, one advantage of doing a field experiment instead of a laboratory experiment is

Option D: Field experiments are better at representing what happens in the real world.

Answer

D. Field experiments are better at representing what happens in the real world.

In the laboratory, the valuables are so much controlled and we work with samples. There are a lot of assumptions that can not be ignored in the real world.

For this reasons, field experiments are better since they represent what happens in the real world.
