BACKGROUND OF THE STUDY
In everyday life, we have goals and objectives of a particular undertaking. At the end of the activity, the goal which one set will be assessed in terms of success or failure and in terms of satisfactory performance or under achievement. If it is possible to describe people psychologically in terms of a special kind, a particular type or as an ordinary number, it would simplify the problem of choosing or selecting. People cannot be categorized or measured as factually and accurately as products or machines. Many men and women may be of the same colour, but they all differ remarkably in height, weight and other less obvious physical characteristics. They will differ too in not easily observed psychological
characteristics as measured intelligence, arithmetic skills, clerical skills, and mechanical aptitude or ability and personality traits. This means that human beings differ in constitutional make up, abilities and potentials are assessed using tests and other measurement instrument.
