Abstract
This study aims to develop simple communicative applications with high accuracy and easy to use by students, teachers, lecturers, or other researchers in the quantitative field. The menus presented have good interconnections, where input-output and data interpretation are carried out in one GUI. We use the Delphi GUI combined with Microsoft Office (Ms. Access, Ms. Excel, and Ms. Word), which is communicative, easy to use, easy distribution (spread), small memory, and portable and desktop-based. The development of this application uses a 4-D development model developed by Thiagarajan namely: Define, Design, Develop, and Disseminate. Based on the results of the development it was obtained the results of expert validation with a validity level of 4.33 which means "Very Good". Then in the limited trial obtained an average score of 4.28 which means "Very Good". While in the phase I and II field trials each of them obtained an average score of 4.21 and 4.22 which both mean "Very Good".
