  1. 1 Introduction to Tests and Measurements

  2. Test and Measurement • Key to life • Everything is tested • Driving, working, eating and sleeping • A to B • Standardization • Fix problems

  3. Test A tool or instrument for measurement Can be written or physical Can take a variety of forms (e.g., subjective, objective, field, laboratory, etc.)

  4. Measurement • Collection of information on which a decision is based. • An objective, nonjudgmental process. • The score

  5. Evaluation A statement of quality. Making an evaluation about a measurement. Can be• Formative-during learning• Summative-end of learning Can be based on• Norm-referenced standards-group• Criterion-referenced standards-pass/fail

  6. Assessment The whole process of test, measurement and evaluation.

  7. What is it?

  8. Testing-How? Reliability-repeatable Objectivity-fact based Validity-truthful Relevance-objectives

  9. Reliable?

  10. Objective?

  11. Valid?

  12. Relevance?

  13. Rater Reliability • Intrarater reliability refers to the same evaluator. • Interrater reliability refers to different evaluators.

  14. Types of Validity • Content-measure what is covered • Construct-measure a concept • Criterion-outcomes/predictive

  15. Discrimination Power • Avoid “ceiling effects”- test too easy • Avoid “floor effects” – test too hard

  16. Performance Standards • Evaluated relative to a peer group (norm-referenced standards). • In relation to predetermined, desired outcomes (criterion-referenced standards)

  17. Norm/Criterion?
