![]() When we think about the reliability of these variables, we want to know how stable or constant they are. ![]() Its degree of reliability has to do instead with the predictability of its relationship with whatever is being tested. In quantitative research, the measurement procedure consists of variables whether a single variable or a number of variables that may make up a construct see the section on Constructs in quantitative research. It might always register three degrees too high, for example. Note, however, that the thermometer does not have to be accurate in order to be reliable. A thermometer that lacks reliability would change even when the temperature does not. If the temperature in a room stays the same, a reliable thermometer will always give the same reading. Imagine that you’re trying to assess the reliability of a thermometer in your home. Intercoder reliability estimation Approaches in marketing: A generalizability theory framework for quantitative data. ![]() ![]() In quantitative research, measures must be reliable in order to claim for the validity of the findings. ![]() Four methods sociologists can use to assess reliability are the test-retest procedure, the alternate forms procedure, the split-halves procedure, and the internal consistency procedure. Reliability means dependability or trustworthiness.Good measurement instruments should have both high reliability and high accuracy.If a measurement instrument provides similar results each time it is used (assuming that whatever is being measured stays the same over time), it is said to have high reliability. ![]()
