- Identify and describe two (2) factors that affect reliability coefficients. Be sure to define reliability coefficient in your answer before explaining how the two factors affect reliability coefficients.
- What is the test-retest method of estimating reliability? Describe the type of study that would be needed to find evidence of test-retest reliability. When is this method best used? When should it not be used?
- Fully explain the relationship between reliability and validity.
- Identify the steps of a criterion-related validation study. Be sure to define criterion-related validity in your answer.
- Define standard error of measurement. Describe its relationship to confidence intervals (you will need to define confidence intervals in your answer)
- What is restriction of range? What is its effect on the validity coefficient? Provide an example of this concept
