This study investigated the influence of stress-induced factor as determinants of undergraduatesâ€™ numerical reasoning and decision making processes (NRDMP) in pseudo-mathematics courses. The study employed descriptive research of the survey type.A sample of 200 undergraduates was selected using purposive sampling technique. A questionnaireused to collect data for this study was tagged Stress Induces Factors among Pseudo-Mathematics Undergraduates Questionnaire (SIFPMUQ). The face and content validity of the instrument were ensured. The reliability of the instrument was established using test-retest method while Pearsonâ€™s Product Moment Correlation analysis which yielded the reliability coefficient of 0.78 was obtained. The data collected was analysed using inferential statistics of t-test and Regression analysis. The finding of the study revealed that exposure to environment has positive influence and relationship onnumerical reasoning and decision making. It also revealed that academic workload, financial issues and making new friends has negative relationship and influence on numerical reasoning and decision making. It also showed the regression model â€œy = 1.551 + 0.214x1 + 0.069x2 â€“ 0.113x3 â€“ 0.170x4â€ such that exposure to environment (x1) and academic workload(x2) contributed positively to NRDMP among pseudo mathematics undergraduates while financial issues (x3) and making new friends (x4) contributed negatively to NRDMP among pseudo-Mathematics undergraduates. Based on the findings, it was recommended that Students should be allowed to study in a conducive environment. Likewise, parents and guardians should endeavour to meet up with the responsibilities of their wards.
