Development of e-learning and statistical simulation for explorative data analysis based on android

Abstract

Exploratory Data Analysis (EDA) is one of the basic statistics subjects that needs to be studied as a basis for higher processing and analyzing data. This subject is taught in class, but these activities are not necessarily enough to understand the subject. This problem can be solved by learning independently. However, in the process of learning independently there are obstacles such as the unavailability of suitable material so that a search is needed which may not produce anything or if the material is available in book or textbook format, the material is less flexible in its use. An e-learning system needs to be developed to solve these problems. In addition, simulation can also help students' understanding in building knowledge base. Furthermore, the use of smartphones with the Android operating system is the most used by Politeknik Statistika STIS students. Based on these problems, an e-learning system and statistical simulation will be built for this Android-based EDA subject. In its development, we use Java programming language and integrate with R Shiny for statistical simulations in the form of data processing. Evaluation shows that the system can be accepted by users as indicated by the Black Box test results and the SUS value of 84.13. The system still consist of basic features and still need to be improved with advanced features so can support the learning activities of EDA.
