An objective test is a psychological test that measures an individual's characteristics in a way that is independent of rater bias or the examiner's own beliefs, usually by the administration of a bank of questions that are marked and compared against exacting scoring mechanisms that are completely standardized, much in the same way that examinations are administered. Objective tests are often contrasted with projective tests, which are sensitive to rater or examiner beliefs. Projective tests are based on Freudian Psychology (Psychoanalysis), and seek to expose the unconscious perceptions of people. Objective tests tend to have more validity than projective tests, however they are still subject to the willingness of the subject to be open about his/her personality and as such can sometimes be badly representative of the true personality of the subject. Projective tests purportedly expose certain aspects of the personality of individuals that are impossible to measure by means of an objective test, and are much more reliable at uncovering "protected" or unconscious personality traits or features.
An objective test is built by following a rigorous protocol which includes the following steps:
- Making decisions on nature, goal, target population, power.
- Creating a bank of questions.
- Estimating the validity of the questions, by means of statistical procedures and/or judgement of experts in the field.
- Designing a format of application (a clear, easy-to-answer questionnaire, or an interview, etc.).
- Detecting which questions are better in terms of discrimination, clarity, ease of response, upon application on a pilot sample.
- Applying a revised questionnaire or interview to a sample.
- Using appropriate statistical procedures to establish norms for the test.
Famous quotes containing the words objective and/or test:
“Children should know there are limits to family finances or they will confuse “we can’t afford that” with “they don’t want me to have it.” The first statement is a realistic and objective assessment of a situation, while the other carries an emotional message.”
—Jean Ross Peterson (20th century)
“I am willing, for a money consideration, to test this physical strength, this nervous force, and muscular power with which I’ve been gifted, to show that they will bear a certain strain. If I break down, if my brain gives way under want of sleep, my heart ceases to respond to the calls made on my circulatory system, or the surcharged veins of my extremities burst—if, in short, I fall helpless, or it may be, dead on the track, then I lose my money.”
—Ada Anderson (1860–?)
