To use the concept of probability and uncertainty estimation is a common practice in daily life. To assist students in learning the fundamentals of probability and statistics, not through the usual class and note taking, a group-learning and practical "statistical system" was designed. By connecting with the main statistical center, students not only can learn the concept of statistics through a group of well-designed activities but also get experience in "crunching" data and "seeing" the results in a more intuitively way to solve their problems. Detailed curriculum contents are presented. The statistical activities consist of two parts. The first part contains games which pertain to the basic understanding of probability, and the other part contains activities which relate to estimation and hypothesis testing of population parameters.
