Influence of Physiological Variables on Senior Secondary School Student’s Performance in Volumetric Analysis in Ekiti State

This study investigated the influence of physiological and variables on senior secondary school students’ performance in volumetric analysis in Ekiti State. The study specifically examined the influence of physiological variables (fatigue, students’ health, time of learning and age) on senior secondary school students’ performance in volumetric analysis. The study adopted the descriptive research design of a survey type. The population of the study comprised of all the 4,675 senior secondary two students in the public senior secondary schools in Ekiti State in the 2021/2022 academic session. The sample for this study was 300 senior secondary school two (SSS II) students that were selected across the three senatorial districts in Ekiti State. Multi-stage sampling procedure which involved, simple random technique was used to select sample for the study. Two sets of instruments tagged “Performance in Volumetric Analysis Test (PVAT) “and “Influence of Physiological Variables on Students’ Performance in Volumetric Analysis Questionnaire (IPVSPVAQ)†were used for the study. The two instruments were validated by experts with PVAT and IPVSPVAQ yielding reliability coefficients of 0.91 and 0.87 respectively. The data were analysed using descriptive and inferential statistics. The descriptive statistics of percentage, standard deviation and histogram were used to answer the research questions while the inferential statistics involving correlation matrix, Multiple Regression and t-test were used to test the hypotheses. All the hypotheses were tested at 0.05 level of significance. The study showed that health, fatigue and time were physiological variables influencing senior secondary school students’ performance in volumetric analysis. It was also found out that there was significant influence of physiological variables on senior secondary school performance in volumetric analysis. It was recommended that there is need to expose students to the influence of physiological variable on their academic performance in Chemistry in order to be able to be improved in their academic performance.
