Chyna is conducting a study with college students reading science texts that explores the role of interest apart from knowledge as articulated in Patricia Alexander's Model of Domain Learning.

Chyna's research problem is best described as a study that:a. tests theory. b. is a replication. c. is developed from a library search. d. comes from personal experiences.

The correct answer is letter A

Classical test theory first appeared in the 20th century from Spearman's work. It can, in some way, be considered the beginning of psychometry. The word test, in this concept, refers to tests designed to assess knowledge, skills or functions.

In psychology, tests are tests of a psychological or psychotechnical character to study or evaluate a function. Thus, psychological tests are tools designed to assess or measure an individual's psychological characteristics.

Tests are sophisticated measuring instruments that, in many cases, are invaluable help in the context of a psychological assessment. For this to be the case, the test must meet minimum psychometric requirements and the specialist who applies it must know the administration protocol and respect it.

On the other hand, test theories tell us how we can assess the quality of a test, and also, in many cases, how we can debug the instrument to reduce error to a minimum. In this sense, perhaps the two most important concepts within the classical test theory are reliability and validity.
