A non-profit public policy "think-tank" organization is planning to conduct a survey examining the condition of low-income families nationwide. The questionnaire covers many topics including family income, participation in state-run welfare programs and health insurance programs for low-income families, children's education and health status, and employment status of parents. Low-income families in rural and inner city areas are of special interest to the researchers. The researchers are considering two modes; a CATI telephone survey or CAPI face-to-face interviews. Discuss the advantages and disadvantages of each mode choice for this project.
