Teaching Statistics using traditional method tend to be quite time consuming which will result to insuffiency to higher competencies. This research on utilizing Scientific calculator in teaching selected topics in Statistics was conducted in one state university involving 30 senior high school students. The primary goal of the study was to attain higher competencies in Statistics by mastering the basics with the aid of scientific calculator. A quasi-experimental design with one sample pre-test post-test approach was used. The statistical tools used in the data analysis were the descriptive statistics and paired t-test. The findings from the study showed that there is a significant improvement in the respondents level of competencies in descriptive Statistics after the utilization of scientific calculator. It was also found out that students showed higher competencies in higher statistical concepts (inferentials) after applying their learnings on descriptive Statistics. Finally, the research concluded that teaching Statistics using Scientific Calculator helps students achieve higher learning in advanced statistical concepts.
