Assessment Reliability

Which source of evidence is most affected by the halo effect or teacher fatigue?

• Stability

• Internal consistency

• Scorer Consistency

• Equivalent forms

What does it mean if you have a low error in your scores?

• Low reliability

• No reliability

• Excessive reliability

• High reliability

Most reliability procedures:

• Overestimate the amount of error

• Accurately estimate the amount of error

• Underestimate the amount of error

This type of error is from the influence that is outside the person

If a scale shows that someone consistently weighs 5 pounds more than they do, the results are:

• Valid and Reliable

• Reliable but not Valid

• Valid but not reliable

• Neither valid nor reliable

One of the factors influencing reliability estimates is NOT:

• Spread of Scores

• Objectivity in Scoring

• Equivalent Forms

• Difficulty in Assessment Items

the extent to which assessment scores are dependable and free from error is:

• Assessment reliability

• Assessment validity

• Internal error

• external error

Estimates consistency of scores measuring the same trait obtained from a single administration of the assessment

• Stability

• Internal Consistency

• Scorer Consistency

• Equivalent Forms

Estimates consistency of scores obtained from two forms of the same assessment, given at the same time or with a time interval

• Stability

• Equivalent forms

• Internal Consistency

• Scorer Consistency

Estimates consistency of scores from two administrations of the same assessment to the same individuals with a time interval between the assessments

• Stability

• Equivalent forms

• Internal Consistency

• Scorer Consistency
