All of these factors can contribute to measurement differences, whether by random or systematic error. Characteristics of individual respondents, short-term personal factors, and situational factors can all affect the way respondents answer a questionnaire or participate in a study, leading to variation in responses. Additionally, the sampling of items included in the questionnaire can also introduce error if the items do not capture the full range of the construct being measured.
