Quizplus · Accepted Answer

By asking people to call in with their responses, this is a self-selected sample as individuals are choosing to participate in the survey. This may introduce biases as individuals who are more likely to participate may have different spending habits compared to those who do not call in. A stratified or cluster sample would require some type of pre-defined grouping or location to select individuals from, and a systematic sample would involve selecting individuals at predetermined intervals.
