A Few Years Ago, Researchers Ran an Experiment Looking at the Influence

Essay

A few years ago, researchers ran an experiment looking at the influence of food sampling in stores on consumer behavior.The main independent variable was whether or not the test participant received a free in-store food sample (half of the participants received a free in-store sample of a small donut and half of the participants were given nothing).The main dependent variable was how much overall food the person purchased in the store.
Given what you know about perception and sensory marketing, what would you predict the main effect in this experiment to be? (In other words, what impact, if any, should an in-store food sample (vs.no food sample) have on
overall food purchases? Justify your answer.
