Estimation of Transformed Continuous Assessment Scores of Rural and Urban Secondary Schools

Abstract

This study examined the transformed continuous assessment CA scores of Osun State junior
 secondary schools with a view to providing information on the procedure for transforming CA scores
 for better comparability of scores among rural and urban secondary schools. The study adopted the
 ex-post-facto research design. The population for the study comprised all junior secondary school
 class III students who had CA scores during 2010/2011 session in both rural and urban secondary
 schools in Osun State. The sample consisted of 1200 students selected using multistage sampling
 technique. A proforma titled Continuous Assessment Scores Retrieval was used to collect CA scores
 of the selected students in English Language and Mathematics. Data collected were analyzed using
 percentages and Pearson’s Product moment correlation statistics. The results showed that the
 transformed CA scores of rural and urban secondary schools were above the mean score in
 Mathematics (62.70%) and English Language (66.0%). The result also showed that there was a
 significant positive relationship between the transformed CA scores and raw CA scores obtained by
 students in Mathematics and English Language (r=1.00; p
