In acknowledging the similarity of purpose of both quantitative and qualitative research, I will proceed to describe the soundness of my methodology.
External validity is still applicability or generalizability.
Reliability denotes consistency, and objectivity is seen as neutrality. The conventional semantics of rigor, however, may induce a reviewer of qualitative research to judge it in conventional terms. Herein lies the controversy. Lincoln and Guba offer another set of terms. An inaccurate description is the single-most important threat to validity.
