The scale of preference refers to a list of a consumer's wants or desires arranged in order of importance or priority. It shows the consumer's preferences or choices among different options. The scale of preference is subjective and varies from person to person.
For instance, if a person is given the choice to buy a new smartphone, a new pair of shoes, or a ticket to a concert, they may rank these options in order of priority. If they value communication more than entertainment, they may choose the smartphone as their top priority. Conversely, if they value entertainment more than communication, they may choose the concert ticket.
Thus, the scale of preference is a way to understand how consumers make choices based on their preferences and priorities, and it helps in predicting their behavior in the market.
