Normal Distribution with Halfway Markers
Description
This 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). Bed Temp: 110 C, Extruder: 240 C, Settings Were On Quick Print.
