This research investigates how feature characteristics affect the academic achievement of Grade 11 students in the field of statistics, with a particular emphasis on the role played by the use of calculators. The control group utilized various scientific calculators that are typically employed in statistics classes. The experimental group utilized the statistical functionalities of the advanced calculator. The objective of this study is to ascertain the impact of statistical characteristics of calculators on the academic achievement of grade 11 students in the field of statistics. The study aimed to determine whether there was a notable disparity between the pretest scores of the two groups. Is there a substantial disparity between the pretest and posttest scores of the groups? Is there a substantial disparity in the gain scores between the two groups? Furthermore, provides a comprehensive assessment of the study. The study's findings indicate a notable disparity in the utilization of various statistical functions on calculators. The experimental group demonstrated superior performance and adeptly utilized the statistical aspects of advanced calculators. The students in the Control group had challenges when attempting to solve the z-test and p-value. The statistical functionality of advanced calculators becomes valuable in advanced statistical topics
