The difficulty of learning statistics from lectures may well account for the widespread bad experiences students and professionals have with introductory statistics courses. Learning pace is under the learner's control. You can pause any activity, repeat any section, or repeat the entire activity as often as you wish. Extensive navigation aides keep you oriented within the course. You always know what you have already covered, what you are currently learning, and what you are about to cover.
Many lessons employ discovery learning.
You discover concepts for yourself by working with an appropriately designed visualization or simulation tool. Concepts discovered yourself are much easier to recall and to integrate with what you already understand. Concepts learned in this way include such traditionally difficult ideas as the Law of Large Numbers, the Central Limit Theorem, the concept of a Sampling Distribution, and the reasoning of Hypothesis Tests. ActivStats provides honest random simulations for studying random phenomena, probability, and inference. Most activities use several communication channels to convey ideas.
