If one respondent gives different answers to the same question at two different points in time, the researcher should be concerned about

Question

Quizplus · Accepted Answer

This situation indicates a lack of consistency in responses, which is a concern for reliability. Reliability refers to the consistency and stability of measurements over time or across different researchers. If responses are not consistent, it is difficult to draw valid conclusions from the data. Validity, on the other hand, refers to the accuracy and truthfulness of the data, rather than its consistency. Representativeness pertains to an accurate reflection of the characteristics of the population being studied, and the Hawthorne Effect refers to the possibility that participants may change their behavior because they know they are being observed. Neither of these concepts is directly relevant to the situation described.
