Measurement and Scaling: Noncomparative Scaling Techniques

Noncomparative Scaling Techniques

* Respondents evaluate only one object at a time, and for this reason noncomparative scales are often referred to as monadic scales.

* Noncomparative techniques consist of continuous and itemized rating scales.

Continuous Rating Scale

Respondents rate the objects by placing a mark at the appropriate position on a line that runs from one extreme of the criterion variable to the other. The form of the continuous scale may vary considerably.

 How would you rate Sears as a department store?

RATE: Rapid Analysis and Testing Environment

A relatively new research tool, the perception analyzer, provides continuous measurement of “gut reaction.” A group of up to 400 respondents is presented with TV or radio spots or advertising copy. The measuring device consists of a dial that contains a 100-point range. Each participant is given a dial and instructed to continuously record his or her reaction to the material being tested

As the respondents turn the dials, the information is fed to a computer, which tabulates second-by-second response profiles. As the results are recorded by the computer, they are superimposed on a video screen, enabling the researcher to view the respondents' scores immediately. The responses are also stored in a permanent data file for use in further...
