Question

Quizplus · Accepted Answer

The correlation coefficient is commonly used as a measure of reliability, and is called the reliability coefficient. Option A (true score) typically refers to the hypothetical, unobservable "true" value of a variable being measured, and is not necessarily related to reliability. Option B (measurement error) is the opposite of reliability and refers to the amount of variation in a measurement that is not due to the actual construct being measured. Option D (reactivity measure) refers to the possibility that participant behavior may be influenced by the knowledge that they are being measured, and is not directly related to reliability.
