Dyad relationships involve a link between a pair of individuals where one individual’s response is not independent of the other’s response (non-independence). Due to non-independence, conventional statistical methods may lead to incorrect statistical conclusions. The purpose of this symposium is to introduce dyad data structure, design, and analysis; describe what happens when non-independence is ignored, and demonstrate how advance statistical methods, such as hierarchical linear modeling, can be used to analyze dyadic data.
