<shameless plug>For other adults interested in learning math, check out my (nonfree) book here: https://noBSmath.com/ PDF preview and sample chapter: https://minireference.com/static/excerpts/noBSmath_v5_previe... I also have a longer book that includes calculus and physics (cf. links in profile). </shameless plug>

Statistics is by far the hardest subject I've had to write about, as I had to (re)learn pretty much everything. I did several rewrites (working on tis book for the past seven years!), but now it's finally ready to ship.

ETA July for digital download, then one round of copy-editing, and September for first print version.
