This study aimed to investigate the effects of spreadsheet application in teaching Data Management in Mathematics of the Modern World on the students' performances among first-year College Students during the Second Semester of School Year 2022-2023. A quasi-experimental research design with the pretest-posttest non-equivalent groups design was employed in the study with the researcher–made questionnaire comprising 40 items test. The statistical methods used to gather data were treated using mean, t-test for independent samples, z-test for correlated samples, and standard deviation. Data were gathered from the 74 first-year college students in Jose Rizal Memorial State University–Main Campus. Results revealed that the pre-test and post-test performance of the students in the control and experimental groups was good. But their post-test performance in the experimental group was excellent. It is concluded that Spreadsheet Application is a very important and effective tool in teaching Data Management in Mathematics of the Modern World to first-year college students. Its application tremendously increases students' performance from the pre-test to the post-test.
