Example text

Guilford, 1956; Nunnally, 1978). g. Cattell and Kline, 1977). Cattell argues that high internal consistency is actually antithetical to validity on the grounds that any item must cover less ground or be narrower than the criterion we are trying to measure. Thus, if all items are highly consistent, they are also highly correlated, and hence a reliable test will only measure a narrow variable of little variance. As support for this argument it must be noted (1) that it is true that Cronbach’s alpha increases with the item intercorrelations, and (2) that in any multivariate predictive study, the maximum multiple correlation between tests and the criterion (in the case of tests items and the total score) is obtained when the variables are uncorrelated.

Most tailored tests use items calibrated from item-characteristic curves so that accurate estimates can be drawn from subsets of items. Such tailored testing is indubitably valuable in practical testing where time is important. Computer testing Computer testing at its simplest involves presenting the items of a test on a computer screen and recording the response from the computer’s keyboard or from a specially built response keyboard. At the end of the test the computer can display the subject’s score and a simple interpretation based upon the norms of the handbook which have been inserted into the computer’s memory.

The check as to whether or not items fit the model relative to a number of populations will be called the among-population item-fit. The procedure for making this check arises directly from the property that the item parameter estimates should be independent of which subjects have responded to the items. For each item the parameter values obtained from a sample from each population of subjects are compared statistically. For details of the complex estimation equations readers must be referred to Wright (1968) or Rasch (1961).
