"Interpreting Multiple Linear Regression: A Guidebook of Variable Importance." <i>Practical Assessment, Research & Evaluation,</i> 17, no. 9 (2012) Practical Assessment, Research & Evaluation: <a href="https://hdl.handle.net/1911/71096">https://hdl.handle.net/1911/71096</a>.1531-7714https://hdl.handle.net/1911/71096Multiple regression (MR) analyses are commonly employed in social science fields. It is also common for interpretation of results to typically reflect overreliance on beta weights (cf. Courville & Thompson, 2001; Nimon, Roberts, & Gavrilova, 2010; Zientek, Capraro, & Capraro, 2008), often resulting in very limited interpretations of variable importance. It appears that few researchers employ other methods to obtain a fuller understanding of what and how independent variables contribute to a regression equation. Thus, this paper presents a guidebook of variable importance measures that inform MR results, linking measures to a theoretical framework that demonstrates the complementary roles they play when interpreting regression findings. We also provide a data-driven example of how to publish MR results that demonstrates how to present a more complete picture of the contributions variables make to a regression equation. We end with several recommendations for practice regarding how to integrate multiple variable importance measures into MR analyses.engArticle is made available in accordance with the publisher's policy and may be subject to US copyright law.
