ASHA Learning Pass

This journal self-study course is composed of papers from a 2019 Research Forum, Advancing Statistical Methods in Speech, Language, and Hearing Sciences. These selected articles provide advanced-level discussion about clinically relevant statistical methodologies to give audiologists a strong foundation from which to analyze and understand the statistical research they come across to decide when and how to apply it in practice. The articles examine frequential and Bayesian statistical methods as well as propensity scores and linear-mixed model analyses.

Learning Outcomes
You will be able to:

• Describe best practices in basic and more advanced inferential statistics that avoid errors and find true clinical significance
• Summarize the difference between frequential and Bayesian analyses as well as potential applications of each
• Explain how propensity score matching reduces selection bias for studies in which randomized control trials are not feasible
• Explain how linear-mixed model analysis improves statistical accuracy in cases of missing data

Assessment Type
Self-assessment—Think about what you learned and report on the Completion Form how you will use your new knowledge.
