Overall, all students could expand their knowledge through visual simulations, while students who could manipulate statistical graphics in the simulation alone were significantly faster. Currently, interactive learning tools that explain statistical concepts are widely used, but only a few are being tested. Well-structured interactive tutorials with visual simulations have proven effective in the past. Through the application of effective instruction design principles, an online tutorial was developed in which students could either manipulate or only observe changes in the visual simulations. Practical implications and possibilities for further investigations in this research project are discussed.
