Validity
Definition
Validity refers to how well something measures what it claims to measure or how accurate and reliable its results are.
Analogy
Imagine taking an online quiz with questions related to geography. If those questions accurately test your knowledge in geography, then we can say that the quiz has high validity. However, if it asks irrelevant questions about cooking, then its validity would be questioned.
