Witryna3 lip 2024 · Reliability refers to how consistently a method measures something. If the same result can be consistently achieved by using the same methods under the same circumstances, the measurement is considered reliable. You measure the temperature of a liquid sample several times under identical conditions. WitrynaValidity should be viewed as a continuum, at is possible to improve the validity of the findings within a study, however 100% validity can never be achieved. A wide range of different forms of validity have been identified, which is beyond the scope of this Guide to explore in depth (see Cohen, et. al. 2011 for more detail).
