Methodology, Research, & Statistics: Tests & measures resources

The Walden Library has resources to help you identify and access research tests and measures, and to obtain the needed permissions to use the tests.

Types of Tests

Tests and measures are tools that can be used for diagnosing, researching, and assessing phenomena in the social sciences, education, and health, and other areas.

Instruments are either published or unpublished.  


When we talk about tests being published that means that they are owned by, and available through, commercial publishers. These tests need to be purchased from the publisher. Published tests are also referred to as commercial.


When we say that a test is unpublished this doesn't mean that it is unavailable in print; it means that it is not a test that you will find through commercial publishers.  Unpublished tests often appear in journal articles, books, and dissertations. Unpublished tests are also referred to as non-commercial.
