While reliability and validity are related, it is possible for a measure to have high reliability and low validity or vice versa. Reliability refers to the consistency or stability of scores obtained from a measure, whereas validity refers to whether the measure actually assesses what it is intended to assess. Thus, a measure may be consistent in producing the same scores over time (high reliability), but may not actually be measuring the intended construct (low validity).
