A high level of ________ measurement error leads to low reliability.
A) systematic
B) true
C) random
D) observed

Question

Quizplus · Accepted Answer

Random measurement error refers to unpredicted fluctuations in measurement that are not related to any systematic factors. When such errors occur at a high level, they can lead to low reliability, as they can produce inconsistent results that do not accurately reflect the true score of a construct. Systematic measurement error (choice A) refers to consistent biases or distortions in measurement that affect all measurements in a similar way and can also bias results in a non-random manner. True score (choice B) refers to the hypothetical construct score a person would get if there were no measurement error or social desirability bias. Observed score (choice D) refers to the actual score a person gets on a given measurement instrument.
