| Abstract | Confidence weighting (CW) tends to improve the reliability of easy tests; the Coombs-type multiple-response (MR) option tends to improve the reliability of hard tests. It was hypothesized that, on a test of moderate difficulty, offering both the CW and MR response options would improve reliability more than either alone. Twenty-four subjects took a 20-item multiple-choice test under CW plus MR instructions. MR was used less than CW; 9 subjects used both options. Coefficient alphas computed on four scoring bases showed MR, alone, depressed reliability a little; CW, alone, depressed it a lot; and the two combined depressed it even more. It was concluded that these two previously successful special testing procedures cannot be combined to form an even better one. (Author) |
