accuracy and validation studies

Accuracy studies evaluate how well a test or tool correctly identifies or measures what it's supposed to, such as detecting a disease or measuring a skill. Validation studies assess whether a test consistently produces reliable and meaningful results in real-world settings, confirming its usefulness and applicability. Together, these studies ensure that a method is both correct in its measurements and dependable over time, helping decide if it’s suitable for practical use in medicine, research, or other fields.
