The effectiveness of the Coombs elimination procedure was evaluated with 29 college students enrolled in a statistics course. Five multiple-choice tests were employed and scored using the Coombs procedure. Results suggest that the Coombs procedure decreased guessing, and this effect increased over the grading period.

Test-Retest Reliability of Computer Based MCW-APM Test Scoring Methods.

Abedi, Jamal; Bruno, James – Journal of Computer-Based Instruction, 1989

Reports the results of several test-reliability experiments which compared a modified confidence weighted-admissible probability measurement (MCW-APM) with conventional forced choice or binary type (R-W) test scoring methods. Psychometric properties using G theory and conventional correlational methods are examined, and their implications for…
