Standard Normal Distribution Model (With Mean and Standard Deviation lines)

thingiverse

This is a standard normal distribution as it's defined from -3 to +3 standard deviations. The standard normal distribution is an essential tool in statistics, developed from earlier models that weren't quite as useful as intended. That model was made from someone else's, which can be found in the remixed section or by going to thing 185896. The lines carved into this model approximate the mean and 1, 2, and 3 standard deviations out from the mean. The third standard deviation mark is the end of the tails on the model. To learn more about normal distributions or standard normal distributions, feel free to leave a comment or ask - or search for it yourself. Also let me know if you have any issues with the model; I'll be happy to see if there's anything I can do to help. This was printed with HIPS on a Lulzbot TAZ 5, originally created to assist a blind student in a social sciences statistics course. Print Settings: Printer Brand: LulzBot Printer: TAZ 5 Rafts: No Supports: No Resolution: Do not recall Infill: 20% Notes: I printed this thing with Brim, 5mm, which helped because previous iterations had curled up tails. This print was in HIPS though, so I don't know if the same problems would be encountered with other materials.
