Determine and Estimate the Numerical Aptitude of Delta State Senior Secondary School Students (Published)

In order to determine and estimate the numerical aptitude of Delta State Senior Secondary School Students, the researcher developed a Numerical Aptitude Test (NAT). The design of the study was instrumentation research design based on the Classical Test Theory. From a population of 4,379 senior Secondary School Students in Delta State, 576 students were drawn from Senior Secondary School I & II as sample for the study. Three research question were proposed and answered. Three hypothesis were formulated and tested at 0.05 alpha levels. Data were analyzed using Kuder-Richardson formula 20, descriptive statistics and t-test. The findings showed reliability coefficient of 0.66. The result also showed that NAT items are valid and did not differentiate between genders. Based on the findings from this work, the researcher made the following recommendations: the Ministry of Education Delta State   should use the developed NAT as a tool for selecting students, also school administrators should use the developed test to get valid, reliable and usable relevant information about Senior School Student’s numerical aptitude for administrative functions.
