    A comparative study of two methods of detecting test item bias in senior schools certificate (SSC) mathematics examination
    (Department of Educational Foundation and Counseling, Faculty of Education, Obafemi Awolowo University, Ile-Ife., 2006) Adediwura, Alaba Adeyemi
    The study examined the occurrence of test item bias in the senior school certificate (SSC) Mathematics examination conducted by West African Examination Council (WAEC) and National Examination Council (NECO) using Scheuneman and the Full Chi-Square methods with a view to determining the relative effectiveness of the chi-square methods in detecting the nature and extent of item bias. In conclusion, Full Chi-Square method demonstrated greater ability to detect test bias in SSC Mathematics examination than the scheuneman chi-square method. Furthermore, most of the biased items measured skills on plane geometry and this was indicative of the need to view some aspects of the test development and validation process of the SSCE.
