This Rating Chart determines how well a measurable quality, such as customer satisfaction, meets expectations. A rating chart is a common data collection method used to gather comparative information about a specific research topic. A rating scale, in particular, is a type of multiple-choice question that allows survey respondents to assign a monetary value to a product or service. A good example is a temperature scale in Fahrenheit/Celsius where the differences between numbers matter, but zero placement does not. Some data are measured on a ratio basis. Numbers indicate the magnitude of the difference, and there is a fixed zero point.
