Define reliability. What are the factors that affect the reliability of a score?
What will be an ideal response?
Reliability is the extent to which a test produces consistent, reproducible scores. Reliable scores are stable, dependable, and relatively free from errors of measurement. Reliability is reduced by errors in measurement. A student can have adequate knowledge and skill and still not perform consistently across several assessments because of a number of factors. Internal factors can include health, motivation, and anxiety. External factors can include inadequate directions given by the teacher, ambiguously created items, poor sampling of information, and inefficient scoring of the student's responses.
