CommunityData:StatsGaps

Welcome to the StatsGaps StudyGroup page -- a set of suggested learning pathways making use of course resources produced by community data faculty, meant to be used by folks who have a mixture of familiarity and non-familiarity with R, statistics, and research processes. The primary text is: Open Intro to Statistics

We borrow heavily from the course most recently taught by Aaron: Statistics_and_Statistical_Programming_(Spring_2019)

To support participation from people with ranging prior experiences and learning goals for this summer, we've organized this content into the following strands:


 * Learn R -- you don't know R
 * Learn Stats -- you haven't taken much if any statistics, or otherwise feel you're mostly starting from scratch
 * Refresh -- overview and shore up your stats knowledge if it feels rusty
 * Stronger -- your stats knowledge is strong but your class stopped before you got to good stuff you see used in lots of the papers in this group (e.g. regression)

Depending on which strand(s) best apply to you, we provide different recommended readings and assignments each week.
