Reliability refers to the degree to which scale produces consistent results, when repeated measurements are made. whether repeating the measurement yields consistent results. For example, if a weight measuring scale is wrong by 4kg (it deducts 4 kg of the actual weight), it can be specified as reliable, because the scale displays the same weight every time we measure a specific item. It refers to the extent of applicability of the concept to the real world instead of a experimental setup. Measures that are high in reliability should exhibit all three.
