Abstract



Previous publications on hierarchical linear modeling (HLM) have provided guidance on how to perform the analysis,yet there is relatively little information on two questions that arise even before analysis: Does HLM apply to one’s data andresearch question? And if it does apply, how does one choose between HLM and other methods sometimes used in thesecircumstances, including multiple regression, repeated-measures or mixed ANOVA, and structural equation modeling or pathanalysis?


The purpose of this tutorial is to briefly introduce HLM and then to review some of the considerations that are helpful inanswering these questions, including the nature of the data, the model to be tested, and the information desired on the output.Some examples of how the same analysis could be performed in HLM, repeated-measures or mixed ANOVA, and structuralequation modeling or path analysis are also provided
