| Research Abstract |
In this research, the system for educational testing data was developed. The developed system enables us to estimate parameters of various types of items based on Item Response Theory which is widely used in psychology and educational psychology. In this research, 1. The parameter estimation programme for Item Response Theory was developed. 2. Multivariate-beta distribution was formulated, and the finite fixture distribution of the distribution was also proposed, which covers entire range of the multivariate testing scores. 3. The Computer-based Testing system has been developed, which shows items to respondents via WEB server, and stores responses of the respondents.
