Imagine that you want to develop a test to measure depression. You gather a set of 100 potential test items and ask a sample of people diagnosed with clinical depression and a sample of nondepressed people to respond to the items. For your final version of the test, you decide to keep only the 15 items that the depressed and nondepressed groups answered differently. You are using a(n) ________ method of test construction.

Answer: The correct answer is: Empirical method of test construction.Explanation: The empirical method can be understood as an approach to test construction in which data is statistically analyzed. First, research items are applied to the participants, then the researchers analyze the responses to find relationships among said item responses to prove or disprove the research hypothesis. In this particular case, an instrument with 100 potential test items was given to two research groups.After they responded to them, only 15 items that the depressed and nondepressed answered differently were chosen for the final version of the test. This shows the process of the Empirical Method of test construction: 1-Item selection 2-Item application 3-Data analysis.In conclusion, the correct answer is Empirical.
