Explanation:Internal and external validity makes the research trustworthy and meaningful.
Internal validity refers to when cause and effect relationship of a treatment and outcome can be trusted.Internal validity also occurs when there is no alternative explanation for a finding.

Internal validity is then how confident one is to the result of the research.
