The quality of any test or assessment instrument used by a forensic psychologist is directly related to how that test was constructed and with whom it was intended for use. Statistical concepts such as validity, reliability, and norming sample population are all built into an instrument during its construction. To this effect, there are various ways of measuring validity and reliability that are applicable to different assessments.
