- Summary:
-
The toal score concept is considered from the test user's point of views. The simples kind of total, obtained by adding raw scores on the tests, automatically assigns weights to the tests which are proportional to their standard deviation. When desired or appropriate, tests can be weighted equally in a total by transforming the raw scores on each test so that standard deviations will be the same. This procedures, usually done by converting the scores on each test to scaled scores, does not of itself provide a better measuring instrument. Validation studies must still be conducted. For a particular criterion, the most predictive type of total score is one based on optimum weights for the tests. In some instances, test authors have so constructed their tests that a simple summation of scores is also the best-weighted total for a specific type of criterion. It is not safe to assume this however; the data should be examined carefully. (Author/KM)
