One point that he stresses is that validity, “is not a commodity that can be purchased with techniques” (Brinberg and McGrath, 1985) meaning that the validity of your research isn’t based on the methods that you used. In Maxwell’s chapter on validity he uses the definition “the correctness or credibility of a description, conclusion, explanation, interpretation, or other sort of account” (page 122).
