Guttman scale, scalogram analysis

scalogram method

an ATTITUDE SCALE, named after its designer, Guttman, which firstly assesses whether the attitude to be studied, e.g. racial prejudice, involves a single dimension. If it does, then it will be possible to arrange, hierarchically and ordinally, a series of attitude questions of increasing intensity such that agreement with a given statement implies agreement with statements of lower intensity. That is, they assume that a cut-off point exists within any set of attitude statements such that failure to endorse a particular item means that no item of greater intensity will be endorsed. Respondents’ attitudes can then be compared by a simple score, and any individual's response towards any item is known from this score. In practice, perfect Guttman scales probably do not exist, and a 10% margin of error is generally considered to be acceptable. Compare LIKERT SCALE.
