Final answer:
The correct answer to the question of what type of test gives the same score when scored by different people is option c, objective. Objective tests are designed to minimize scorer bias and produce consistent results based on standardized methods.
Step-by-step explanation:
The correct answer is option c. Objective tests give the same score when different people score it. These tests are designed to be free from individual scorer's biases and interpretations, ensuring consistent results regardless of who administers or scores the test. Objective tests commonly use standardized methods of testing, which include consistent administration, scoring, and interpretation of results. For example, self-report inventories like the Minnesota Multiphasic Personality Inventory (MMPI) are types of objective tests used to assess personality traits and are scored in a standardized manner.
Reliability and validity are crucial when evaluating a test. Reliability refers to the consistency of the measurement, whereas validity pertains to how well the test actually measures what it is intended to measure. A test may be reliable without being valid; however, a valid test is by necessity also reliable. To establish standardization and ensure a test is normed, it must be tested on a representative sample. This helps determine how the test scores compare across a wider population.
