Types of Validity/ Reliability
by April Reed
1. Kuder Richardson methods
1.1. Determines if questions have a common ground and can be put together
1.2. It is a fairly consistent method, it does not change with the each passing test, which leads to better testing
2. Criterion Related Validity
2.1. Predictive Validity
2.1.1. Examines future behavior of examinees
2.1.2. Provides a numeric value to show where the student sits on test
2.2. Concurrent criterion
2.2.1. Offers a test and study test then finds a correlation between the scores
2.2.2. Provides a numeric value which can be illustrated on a chart to show differences
3. Final Thought
3.1. Validity and Reliabilty are important to learning and assessment becuase they can determine
3.1.1. if objectives are being met
3.1.2. assessment question have a common goal
3.1.3. difference in scoring between assessments
3.1.4. if students are grasping the information
3.1.5. if students are understanding the material being taught
4. Test Retest or Stability
4.1. Examines scores between the two test determining if it reliable
4.2. Can show a student's score and give an idea of of how they are doing
5. Internal Consistency
5.1. Split half methods
5.1.1. Test are shorter because the questions are split into two parts
5.1.2. Easier to determine which questions are not meeting the standard
