If the same measure produces different results each time it is administered, it means that it lacks reliability. Reliability refers to the consistency of a measure over time, so if it is not reliable, it cannot be relied upon to accurately measure memory in older individuals. Representativeness refers to the degree to which a sample accurately represents a population, utility refers to usefulness, and validity refers to how well a measure actually measures what it is intended to measure. While these factors can also impact the effectiveness of a measure, the inconsistency in results suggests a reliability issue.
