Why doesn't the presence of measurement error indicate that a researcher has necessarily made a mistake in collecting data?
What will be an ideal response?
Measurement error does not indicate that a researcher has made an error. It means that the data do not perfectly represent the concept of interest. Instead, measurement error reflects the effect on a measurement of some variable that is not of interest in the research. It may reflect poor wording on a questionnaire, temporary inattention by the participant, or a multitude of other factors unrelated to the research.
