Field notes
A student enters the numbers from a problem; StatPi lays out the arithmetic line by line and annotates why each step belongs. Its sample binomial problem moves from choosing the sheet to an R comparison, and the site reports that all 632 checks on the current build match R. Lite runs in a phone browser without an account; the full course version is described as a flat-fee unlock. The homepage identifies Dr. Paul Weiss as a statistics teacher and advertises live Sunday-night sessions.
