Measures of Equivalence as a Predictor of Students Reliability in Biology Objective Tests [ ]


The purpose of the study was to investigate into the measures of equivalence as a predictor of student’s reliability in biology objective test scores in secondary schools. The design of the study was correlation and the population was all the 1756 biology students of the senior secondary school two (SS 2) in the 2013/2014 academic session. Simple random sampling (battling without replacement) was used to sample 450 students from 14 secondary schools in Ezeagu Local Government area of Enugu Slate. The instrument for data collection was biology objective test (BOT). Pearson ‘r’ and t-test were used to correlate and test the hypothesis at 5% level of confidence. Based on the analyzed data, it was found out that out of the 10 schools studied, the measure of equivalence of objective test scores had significant reliability in seven schools. The reliability was significant in the co-educational and boys schools. In the girls' schools, the reliability was not significant
