Which term describes the degree to which repeated measurements show the same result?

• A. Accuracy
• B. Reliability
• C. Precision
• D. Validity

Answer: (C)

Precision is the degree to which repeated measurements show the same result. When you measure the same quantity multiple times and the values stay very close to one another, the method is precise, reflecting repeatability. This focuses on consistency rather than how close you are to the true value. You can be precise but not accurate if those consistent results are far from the actual value. Accuracy, by contrast, is about closeness to the true value. Validity asks whether the measurement actually assesses the intended property, and reliability refers to the overall dependability of the measurement process across trials or conditions. So, repeated, consistent results point to precision.
