The seven-point scale is a measure of the relative knowledge a person reports having about cars and their operation compared to the "average" buyer. Srinivasan and Ratchford (1991) and Sambandam and Lord (1995) used a Likert version of the scale whereas Bottomley, Doyle, and Green (2000) used a semantic differential variation.
Ten, seven-point statements are used to assess a consumer's knowledge about and familiarity with automobiles, at least in terms of the information needed to make a purchase decision. The scale was called product experience by Mason et al. (2001).
An eight-item, seven-point Likert-type scale is used to measure the degree to which a person who has just been involved in a service activity thinks that the person providing the service was effective and performed well. The activity studied by Price, Arnould, and Tierney (1995) was a river rafting trip and the river guide was the service provider being evaluated by the customers.
