These are old presentations I put together shortly after we started online instruction. Back then, you couldn't trust fonts to come out reliably on the other end. If you wanted to be sure your material showed up for a broad range of people with different browsers and such, you had to make everything graphics. Of course, the typical screen size has almost doubled since then, so you may have to zoom these things to read them easily, andthe resolution will still poor by today's standards. Nonetheless, they evolved through several semesters of instruction and they can help you get the most important principles of introductory stats.
