When deciding on a case for the case study, researchers will therefore use information and facts-oriented sampling, instead of random sampling.[twelve] Outlier cases (that is certainly, All those that happen to be Extraordinary, deviant or atypical) expose more information than the possibly consultant case, as noticed in cases selected For additional qualitative basic safety scientific analyses of mishaps.
