Communicating statistical concepts can be a challenging task for applied statisticians, and often requires more than one strategy. A heuristic approach, which encourages self-learning through discovery, can be a useful tool for getting complex ideas across to researchers and others. A heuristic approach conveys a reasonable approximation of the method, without providing an exhaustive technical explanation. In this presentation we illustrate a heuristic approach to explaining random effects in a multilevel model. By using a thoughtful combination of real-world data, illustrative graphs, and pointed questions, the fundamental concepts behind random effects are revealed. This technique has been applied in a graduate class in longitudinal/clustered data analysis for non-biostatistics Public Health students.
