Validity encompasses the entire experimental concept and establishes whether the results obtained meet all of the requirements of the scientific research method.
For example, there must have been randomization of the sample groups and appropriate care and diligence shown in the allocation of controls.
confirm implies the removing of doubts by an authoritative statement or indisputable fact.

Other researchers must be able to perform exactly the same experiment, under the same conditions and generate the same results.
For example, the software will evaluate a plan to add a switch or alter LUN masking, apply simulation to determine the impact of that change, identify steps required in the proper sequence to avoid problems, and severity measurements systems only by expert judgment (of measurement methods or in comparison to expected outcomes), people have turned to correlating severity scores with probability of death after treatment.
These examples are from the Cambridge English Corpus and from sources on the web.
Internal validity dictates how an experimental design is structured and encompasses all of the steps of the scientific research method.
Even if your results are great, sloppy and inconsistent design will compromise your integrity in the eyes of the scientific community.
