摘要： An instructional system or method for statistics students. Twenty slots (30-68) are defined into which one hundred data cubes (72) are placed. The number of cubes (72) per slot (30-68) varies from one to ten, excluding six. The slots (30-68) with ten cubes (72) are arranged adjacent to a centre line (70), and the number of cubes (72) per slot (30-68) drops as the distance between a slot (30-68) and the centre line (70) increases. The cubes (72) model a normal distribution curve and can be used to estimate probabilities and other statistics concepts. The system associates statistics computational methods with the fundamental concepts of statistics in a manner that enhances the students understanding of statistics as a whole.
