psychometric validation

Psychometric validation is the process of ensuring that a test accurately measures what it claims to measure—in this case, general knowledge. This involves assessing the test's reliability (consistency of results over time) and validity (whether it truly reflects a person’s knowledge on a subject). Various statistical techniques are used to evaluate these aspects, ensuring that the questions are appropriate, relevant, and unbiased. A well-validated test provides trustworthy results, helping to determine an individual's general knowledge level accurately.
