VI 23-1 Part : Learning About the World : Chapters 23 25 Now that we have the principles of inference under our belts, its an easy slide downhill to the finish line. The mantra of this Part is just like the other ones, only a little different. Emphasize that, and students wont feel overwhelmed thinking there are new formulas and methods raining down on them with each chapter. If you havent done it yet, point...
