Quizplus · Accepted Answer

Emily is simply counting the number of refrigerators, which is a discrete variable because it can only take whole number values. It is not continuous because it cannot take on any value between two whole numbers. There is no indication that the number of refrigerators is ordinal (i.e. there is no inherent order to the values). There is also no indication that they are measured on an interval scale (i.e. the difference between two values is meaningful).
