Quizplus · Accepted Answer

Characteristics of individual respondents, short-term personal factors, and situational factors can all directly or indirectly affect respondents' answers to survey questions, leading to measurement differences that might be either random or systematic. Similarly, the sampling of items included in the questionnaire may also introduce biased or incomplete measurement data, adding to the measurement error.
