Reliability refers to the consistency or stability of a measurement over time or across different observers. Random error refers to the variability that occurs because of chance factors, such as environmental conditions or individual differences in the people being observed. A reliable measurement is one that is relatively free from random error, meaning that the results are consistent or stable over time or across different observers. Validity refers to the extent to which a measurement actually measures what it is intended to measure. Generalizability refers to the extent to which findings from a study can be applied to other populations or settings. Utility refers to the practical usefulness of a measurement or research finding. Verifiability refers to the ability to replicate or confirm research findings through independent investigation. While all of these factors are important for evaluating research measures, the one that specifically addresses the issue of random error is reliability.
