RELIABILITY
by sayre flannagan
1. Test-Retest: this method can prove reliablity if the scores on both tests correlate positively
2. Alternative Form: By administering two test covering the same topics, the issue with memorization from test-retest is eliminated and if they correlate then the test is reliable
3. Internal consistency: ensures that all of the questions within a test adhere to instructional objectives througout test. By splitting the test in two halves, if a student performs similarly on both halves the test has consistency.
