Is it accurate to conclude that John is twice as motivated as Cindy? Is it accurate to conclude that John is twice as motivated as Cindy? Is it accurate to conclude that, because of her score of 0, Linda totally lacks motivation? Suppose that on item #27, Matthew had circled a rating of 5. What are the real upper and lower limits of this measurement? Would a person's total motivation score - figured by adding up the numbers they circled for each item, be considered a discrete or a continuous variable? How could one measure motivation with a continuous variable?
The amount of motivation of an individual was measured by a self report scale that has 32 items each scaled as shown below: 0........1........2........3.......4..........5.........6...........7 never hardly ever sometimes very often The following scores were obtained: Mishelle 192, Justin 128, Matthe
