We propose a method for on-line detection of examinees' aberrant responses that uses response time data in e-testing. Unique features of this method are: 1. It includes an outlier detection method using Bayesian predictive distribution. 2. It can be used with small-sample sets. 3. It provides a unified statistical test method of various statistical tests by changing hyper-parameters, and it provides more accurate test results than commonly used methods. 4. Outlier statistics are estimated by considering both examinee abilities and the difficulty level of items. We evaluated this system, and results of our evaluation show that it is effective. |
