One of the ways that scientists confirm the validity of a new discovery is by repeating the research that produced it. You step on a new weight scale and see an accurate number on the scale of how much you weigh. This is why the method is named alternate-forms.

If the results are accurate according to the researchers situation, explanation, and prediction, then the research is valid. Quality Research: It is important to understand that although threats to research reliability and validitycan never be totally eliminated, however researchers need to strive to minimize this threat as much as possible. In memory of Bjrn Gustavsen IntroductionIn the varied, not to say confusing, discussion of quality in participatory and action research, the use of reliability and objectivity as notions to understand the topic is largely missing (Herr & Anderson, 2015; Reason, 2006).
