Answer:
Validity.
Step-by-step explanation:
Validity is the soundness of conclusions that can be drawn from an experiment. It is a term used to refer to how precise and accurate a method describes, estimate, and establish what it is supposed to measure or quantify at a given time.
Hence, if an experiment has a high validity, this ultimately implies that its outcome are in correspondence with the characteristics, properties, and as such it has a sound conclusion. Thus, an experiment is said to be valid when it has a great level or soundness of conclusion.
