understanding concepts of measurement and measurement scales

I am attempting to understand measurement and measurement scales in order to measure behavior. I am not able to "get" this.in a manner in which I am confident. Below is what I am working with. 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, Matthew 183, Cindy 51, Julie 218, John 102, Linda 0. a. Is it accurate to conclude that John is twice as motivated as Cindy? Explain your answer being sure to include which scale of measurement is being used.... click for more
