Development of Excel-Based Learning Media to Improve Understanding of High School Statistical Concepts

The development of this product aims to facilitate teachers and students in learning statistics be more efficient so as achieve completeness terms understanding students' mathematical concepts. developed was validated by experts the results showed that valid feasible category applied learning. Furthermore, limited trials were carried out on several see practicality product, getting classified very practical. research continued testing sample for trial selected purposive sampling. This design uses a pretest-posttest control group with 2 classes consisting an experimental class using excel-based media conventional Hypothesis t-test at time pretest there no difference average between two classes, while posttest classes. Followed N-Gain test increase from showing concepts is higher than class. So it can concluded valid, practical, effective increasing
