Question

Quizplus · Accepted Answer

Viewer diaries may suffer from distorted reporting due to memory bias or a tendency to overestimate or underestimate viewing time. Diary fatigue is also a common problem, where viewers may become tired of documenting their viewing habits and become less accurate over time. Therefore, viewer diaries have problems that could impact the validity of the sample.
