Question

Which of these describes something that would increase the validity of an experiment?

A. studying lions instead of tigers
B. presenting your results to the class
C. having no controls for the experiment
D. repeating your experiment many times

Answer 1

The statement that describes something that would increase the validity of an experiment is 'repeating your experiment many times'.

Option: (D)

Explanation:

• For an experiment to be valid, the end result of the experiment has to remain broadly unchanged no matter how many times the experiment is conducted (given that the external conditions are similar).
• In case the experiment fails to deliver the same result more than once, the first obtained result would be deemed as a mere coincidence.
