Statistical thinking for microbial ecology

Most microbial ecologists understand the importance of rigorous statistical analysis for conducting a replicable study. However, formal courses in the statistical analysis of high-dimensional ecological data are rare, and traditional courses in applied statistics may not teach skills applicable to modern microbiome analysis.

This webinar will introduce foundational concepts in statistics, with a focus on applying these concepts to the analysis of modern microbiome datasets. To illustrate these concepts, we will use the field of "differential abundance" as a case study. We will contrast popular differential abundance parameters and estimators, specifically focusing on estimating meaningful contrasts using high-throughput sequencing data.

Who is this course for?
This webinar is suitable for anyone working in microbial ecology. No prior training in statistics is expected, but some familiarity with common tools for data analysis in microbial ecology would be useful.

This event is part of a webinar series that highlights contemporary concepts, methodologies, and valuable resources for examining microbial ecosystems and their influence on the environment and human health.

Outcomes
By the end of the webinar you will be able to:
Distinguish a statistical parameter from an estimator
Identify three challenges in analysing microbial high-throughput sequencing data
Contrast estimating changes in microbial relative abundances with estimating fold-changes in total abundances
