COMPARATIVE ANALYSIS OF STUDENT ENROLLMENT IN EKITI AND OGUN STATE USING SUCCESSIVE SAMPLING ON TWO OCCASIONS

Statistics

In a survey that is repetitive in nature, past values of the variable under investigation may be used as an auxiliary to improve on the precision of the estimate of current occasion. This paper explores the use of Successive Sampling on two occasions to determine the estimate of the mean, minimum variance, maximum precision, estimate of change in mean and estimate of the overall mean of student enrolment in Ekiti and Ogun state. In order to get a clear and complete overview of student enrolment in the states, successive sampling is used. The data is based on students’ enrolment in Ekiti and Ogun State Public Secondary Schools, collected from Ekiti State Ministry of Education Teaching Service Commission and Ogun State Ministry of Education Oke-Mosan, Abeokuta. The current estimate for the student enrolments in Ekiti State Junior Secondary School is found to be 5542 students, compared to Ogun State Junior Secondary School which is found to be 7,557 students. The estimation for the current estimate is more precise when the correlation approaches unity. Also, from the results, minimum variance as well as maximum precision is achieved when correlation is unity. This implies that there is a perfect positive relationship between the first and the second sampling occasions. The results obtained show clearly that Ogun and Ekiti state government should monitor student’s enrolment in every 3 years, so as to make adequate plans and implement competent infrastructure for universal basic education (UBE) and state universal primary education board (SUBEB) in public schools.
