Reliability and Validity
  • Description:
    This clearly-written chapter from an online text deals with 9 test-related topics: (1) What Makes a Good Test, (2) Test Reliability, (3) Interpretation of Test Information from Test Manuals and Reviews, (4) Types of Reliability, (5) Standard Error of Measurement, (6) Test Vality, (7) Methods for Conducting Validation Studies, (8) Using Validity Evidence from Outside Studies, and (9) How to Interpret Validity Information from Test Manuals and Independent Reviews.

  • What to Do:
    1. Click on the colored title of this on-line resource: "Reliability and Validity."
    2. Examine the list of the 9 topics coved in the chapter.
    3. Read the section(s) that correspond with your interests.
    4. Consider reading all 9 sections.

  • Sky Huck's Puzzle Question:
    A portion of Section 4 ("Types of Reliability") deals with internal consistency reliability. However, no specific methods of estimating internal consistency are mentioned. Can you name three relatively population methods for estimating this kind of reliability?
     
Convergent and Discriminant Validity
  • Description:
    This on-line resource focuses on two of the techniques used to assess construct validity. The clearly-written text material and wonderful graphics are bound to help you understand how convergent and discriminant evidence can be used to assess how well a measuring device is "getting at" the construct it's intended to measure.

  • What to Do:
    1. Click on the colored title of this on-line resource: "Convergent and Discriminant Validity."
    2. Carefully read the text and examine all pictures contained within it.
    3. Click (if you wish) on the terms that are highlighted in the text if you'd like to see an explanation of what they mean.

     
Multitrait-Multimethod
  • Description:
    In an effort to help assess construct validity, some researchers use a procedure that goes by the name "multitrait-multimethod." The clearly-written text and helpful pictures contained in this on-line resource will help you understand what's involved which this approach to validation is used.

  • What to Do:
    1. Click on the colored title of this on-line resource: "Multitrait-Multimethod."
    2. Carefully read the text and examine all pictures contained within it.
    3. Click on various terms that are highlighted in the text (e.g., nomological network) if you'd like to see explanations of what they mean.
