The normal distribution comes in really handy when computing confidence intervals and performing hypothesis test, when you have a large enough sample. But when your sample is too small, you'll get better results by using the t-distribution.

Student's t-distribution gets its name because of an anonymous publishing by Gosset back in the 1900's. Today this distribution is widely used by many people in many disciplines. The t-distribution is bell-shaped and symmetric around 0, similar to the standard normal distribution. However, the t-distribution's shape is determined by its degrees of freedom. Small degrees of freedom result in heavy tails and a low peak. As the degrees of freedom increase, the shape approaches the normal.

To help represent the changing shape of the t-distribution three degrees of freedom were chosen, 1, 2, and 200, and are embroidered in shades of gray. On the back of the plushie is a t and a legend for the three curves, as shown in the last image.

This listing is for one anatomically correct* t-distribution plushie. The plushie is made from pre-washed baby blue flannel. All features are hand embroidered. The plushie is gently stuffed with poly-fil.

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

Size: Approximately 10" long and 7" tall
