5.1 Standardization and Norms


  • Norms of a test are the information used to rank scores in relation to other scores on the test.
  • It can also be understood as the scores established from a test.
  • For eg- the mean score of an “xyz” scale was 600.


  • It is a part of test development procedure which includes establishing norms for a large sample.
  • Consistency and objectivity of how tests are administered and scored. In order to compare one person to another on a test, it is important that they take the test under the same conditions and the same scoring procedure is applied to both.
  • Standardizing a test involves administering the test to a sample of future test takers in order to establish a basis for meaningful comparison.
  • So lets take an example to understand it in a better way . Like I have developed a scale in order to understand the personality of Indian school children . Now this scale may be given a large group of school students who differ on factors like age , gender etc .So if you are an 17 year old Indian school going female , your test score should be compared to the scores of others like you and not to American school students .


  • It refers to be free of any personal biasness in respect to the scoring, its administration and the way the scoring is interpreted.
  • For eg- if my research hypothesizes that stress leads to frustration but it was not supported by the results obtained by me, so it will make no sense of me to continue on arguing that it does!! The more objective we are as an researcher the better our research becomes.

For a practical example to understand reliability , validity and norms refer to the following document ( page 145-148)
