SummaryThis is the normal distribution, made with three channeled lines; one to mark the mean, and two to mark what is approximately half way out (s=1.5) on it. This does not mean that 50% of the data would fall between these two lines (quite a bit more, actually; about 86%). This is meant to operate as a physical model for assisting the visually impaired with understanding common statistical problems, such as any queston that asks for what percentage falls between two given z scores. The being able to physically feel the lines gives a better understanding of what the question is asking, even if the lines are not in accurate places. Printed in HIPS on a Lulzbot TAZ (5, I think).

But, when printed with a brim, there is a bit of brim that will be left over on the channels through the underside of the model. I used forceps (tweezers) to peel this brim away.How I Designed ThisAll StepsRemixed ayoung's "Normal distribution sliced to show "68-95-99.7 Rule"" model by removing the numbers and splitting the pieces before sticking them all together. I then took this piece and used it to cut out a section from a (roughly) circumscribed rectangular prism. I then used this cut out on another rectangular prism of the same size to get back to a (now much smoother) curve piece. Then, I made a small rectangular prism (the dimensions of which I forget) and copied it six times, then used it to slice the channels in the model for the markers (cut one body using another).
