This paper introduces a simple, free web app for teaching regression that ``inverts'' the usual pedagogy. Rather than asking students to run regressions on data, it asks them to ``create'' data to achieve a given outcome, like a statistically significant line. By clicking on an (x, y) graph, students watch the regression line update with each mouse click, along with its confidence intervals and test statistics. The exercises presented in this paper are designed to give students an intuitive feel for the relationship between data and regression, and to teach them what regression can and cannot do.
