ITEMS DISTRIBUTION AND RELIABILITY COEFFICIENT OF MATHEMATICS ACHIEVEMENT TEST ADMINISTERED AMONG JUNIOR BASIC SECONDARY SCHOOL STUDENTS IN DELTA STATE

Abstract: The study investigated questions distribution and reliability coefficient of mathematics achievement test administered among junior Basic secondary school students in Delta State. Two research questions guided the study. Instrumentation research design was used for the study. The population of the study was 19, 693 Junior Basic secondary school two (JSII) students in Delta State. The sample size of this study was 900 students drawn from secondary schools. The sample for the study was obtained using the multi-stage sampling procedures. The research instrument was designed by the researcher. The items in the instrument were selected from the SS2 Delta State Ministry of Education curriculum. 150 test items were drawn based on table of specification that covered the contents of Numbers and Numeration, Basic Operations Algebraic Processes Measuration, Geometry and Everyday Statistics. The research question one was answered using frequency and percentage while research question 2 was answered using Cronbach’s alpha reliability coefficient and Test Response Function (TRF). The findings of the study showed that items in the test are evenly and adequately distributed according to the curriculum of Delta State Ministry of Education and reliability coefficient of the mathematics achievement test is 0.96. In line with the findings and conclusions of the study, it was recommended among others that all items having bad difficulty and discrimination should be modified so that they will be useful in the assessment of Junior Basic secondary school students in Mathematics Keywords: Items Distribution, Reliability Coefficient, Mathematics Achievement Test.
