In a study of how people make mindless choices that affect how much they eat, 85 nutrition experts were asked to scoop themselves as much ice cream as they wanted (wansink, ittersum, and painter, 2006). some of them were randomly given a large bowl (34 ounces) as they entered the line, and the others were given a smaller bowl (17 ounces). similarly, some were randomly given a large spoon (3 ounces), and the others were given a small spoon (2 ounces). researchers then recorded the amount of ice cream (volume) each subject scooped for him or herself. their conjecture was that those given a larger bowl would tend to scoop more ice cream, as would those given a larger spoon. a. identify the observational units in this study. b. identify the three variables that were recorded on the observational units in this study. also classify each variable as categorical or quantitative. c. state the two research questions that motivated the researchers to conduct this study
