![]() ![]() If your outcomes differed, then we would say that the test is 'unreliable' because your results were inconsistent.Īnother example is an IQ test. The test should be resilient to certain external factors like your mood or fatigue. If you took the test in the morning and again in the evening, your outcome should be the same. Your personality type is static, meaning it shouldn't change. In case you are unfamiliar with the test, it claims to tell you what Personality Type you are by asking questions about your reactions, motivations, beliefs and behaviors. A good example is the Meyers-Briggs Personality Test. If we are putting in the same input over and over again, we should get the same result. When we discuss consistency we are looking at how well the test functions. We consider them when looking at how a psychologist has created a test and evaluating how good the test is. In short, Reliability refers to consistency and Validity refers to accuracy. 'Consistency' and 'accuracy' are trigger words for examiners, use them correctly and your marker will be confident that you've understood. We talk about Reliability and Validity when we are critiquing a research method. This question slips up a lot of students as the two are easily mistaken for one another.
