Normal Distribution with Halfway Markers

pinshape

Here is the spun text: This is a visual representation of the normal distribution, featuring three distinct lines that work together to convey important information. The central line represents the mean, while the two outer lines indicate the approximate midpoint of the distribution, roughly 1.5 standard deviations away from the mean. This does not necessarily mean that half of the data falls between these two lines, as it actually exceeds this threshold by a significant margin - approximately 86%. This model was designed to serve as a tactile aid for individuals who are visually impaired, helping them to better understand complex statistical concepts such as z scores and the percentage of data that falls within a given range. By physically interacting with the model, users can gain a deeper understanding of these concepts, even if the lines themselves may not be perfectly accurate. The model was printed using a Lulzbot TAZ 5, with a bed temperature of 110 C and an extruder temperature of 240 C. Quick Print settings were employed for this project. Details about the printing process include printer brand (LulzBot), printer model (TAZ 5), raft status (does not apply), support structure type (none), resolution (unknown), infill percentage (20%). In order to achieve a smooth brim, the standard brim option was selected in Cura. Once printed, the model underwent a post-processing step where the excess brim was carefully removed using forceps. A photograph of this process could not be obtained due to excitement and enthusiasm for trying out the new brim feature. However, it is worth noting that when printing with brim, some residual material will remain on the underside of the model, requiring additional effort to remove. To create this model, a remixed version of ayoung's "Normal distribution sliced to show 68-95-99.7 Rule" was utilized as a starting point. The original design was broken down into individual components and then reassembled in a new configuration. This process involved cutting out a section from a roughly circumscribed rectangular prism, which was then used to create a smoother curve piece. Next, a small rectangular prism of unknown dimensions was copied six times, allowing for the creation of channels in the model that would serve as markers.
