Skill Path: Probability and Statistics with R
Probability and statistics are critical in data science. They allow us to gather insights from data and determine whether what we’re seeing is meaningful. This path introduces the basics of statistical analysis using R, including sampling, working with variables, and understanding frequency distribution tables.
