## Item details

Materials

flannel, polyfil, cotton embroidery floss

A common assumption in statistics is that our data come from a normally distributed population. Even though we'd like it to be, this isn't always the case. Sometimes the distribution of our population is down-right skewed (catch that, right skewed?).

One right skewed distribution is the log normal distribution. By definition, data that are log normally distributed can undergo a simple (natural) logarithmic transformation to then follow a standard normal distribution.

This anatomically correct* plushie is made from pre-washed light pink flannel. All details are hand embroidered. There are vertical lines (in either pale teal or lilac) depicting the center of the distribution (where 50% of the area is above and below), then moving out to capture the middle 68% of the distribution, then moving out to the middle 95% of the distribution, and the middle 99.5%. However, only the left-most cut off for the 95% and 99.5% portions of the data are displayed. The right-most cuts of extend beyond this plushie. On the back side of the plushie is an embroidered logN(0,1) denoting that this is a log normal distribution plushie.

*The open-source program R was used to create the pattern.

Size: Approximately 10" wide and 7" tall
