Examining and reporting the status of statistical assumptions in neuropsychological research: A misbegotten ethical obligation?

Abstract

The ethical responsibilities within clinical practice are ubiquitous. Yet, several aspects comprising the clinical neuropsychologist's role, although carrying equal ethical ‘weight,’ may be relegated to a lesser value and are considered irregularly. This paper is of the position that statistical assumptions are arbitrarily and unpredictably reported in research. However, violating statistical assumptions can often yield untenable results, rendering the inferences based on the primary analysis equally precarious. Just as clinicians are enjoined by their respective professional organizations to abide scrupulously by ethical principles in clinical practice, neuropsychologists should be equally careful over such important matters in research. Consistent examination (and rectification when needed) and reporting of the status of statistical assumptions will help to not only broaden and maintain the ambitions of sound ethical practice but, ultimately ensure optimal patient care.
