A researcher asks families to remember every small purchase they made during the previous twelve months. What problem is especially likely?

Answer and explanation

Correct answer: Some purchases may be forgotten or remembered inaccurately

Remembering many small transactions over a long period is difficult. Recall bias can cause errors in reported spending, so records or shorter reporting periods may improve accuracy.
