A researcher for a national restaurant chain is designing an experiment to determine the impact of the waiting time between being seated and first being approached by a waitperson on the likelihood to order dessert after the rest of the meal. She has heard that a survey asking people about their feelings will be less predictive than a causal design using a marketing experiment, so she definitely wants to design and use an experiment.
