Unit 11 : Development of Norms of a Test


                population adequately, due to which a norm developed on a small group can give incorrect  Notes
                interpretation.
            3.  Meaningfulness : By meaningfulness is meant the type of norms. The evolved norms should
                be dependent on the test objectives and measurable traits. Where traits increase with an
                increase in age, it would be proper to develop age norms or grade norms. However, if
                personality has to be measured, then percentile norms or standard score norms should be
                applied. In the same way, if the aim of a test is to ascertain the desirability of a student’s
                physical or educational achievement, then it would be more adequate to use age or grade
                norms, but if the aim of a test is to find out the position of the student in a large group, then
                the percentile and standard norms can be used.
            4.  Comparability : Comparability is an important characteristic of norms. Test norms should
                be mutually comparable, only then these norms can be used to compare different students.
                Besides, norms should be sufficiently described, that is, the different reference points should
                be clearly explained so that the students’ ability can be clearly explained in words.
            In the context of above characteristics of norms, the following precautions should be exercised
            while determining norms :
               (i) Norms should be carefully calculated. For this, scores of a student in different tests should
                  be referred, and not his scores in only one test.
              (ii) The sample used for ascertaining norms should always represent the entire population.
