internal consistency

Internal consistency refers to the degree to which different items or questions in a test or survey measure the same concept or trait. For example, if a general knowledge quiz includes various questions about history, science, and geography, high internal consistency means that participants who know about history are likely to score well in other areas too. This ensures that the test is reliable and that all parts of the quiz contribute to measuring the overall knowledge effectively, rather than assessing unrelated skills or information. It’s essential for ensuring that the results are trustworthy.
