This course will provide biologists and bioinformaticians with practical statistical and data analysis skills to perform rigorous analysis of high-throughput biological data, with applications focused on single-cell sequencing. The course assumes some familiarity with genomics and with R programming, but does not assume prior statistical training. It covers the statistical concepts necessary to design experiments and analyze high-dimensional data generated by genomic technologies, including: exploratory data analysis, linear modeling, analysis of categorical variables, principal components analysis and other dimension reduction methods, multiple hypothesis testing, and batch effects.

  • Source repository
• Secondary: Modern Statistics for Modern Biology by Holmes and Huber
• Lab materials: Orchestrating Single-Cell Analysis with Bioconductor (OSCA) by Amezquita, Lun, Hicks, Gottardo, O’Callaghan

Each day will include a hands-on lab session from Orchestrating Single-Cell Analysis with Bioconductor, that students should attempt in full.
