Statistical Sampling Paddle

thingiverse

I took a Probability and Statistics class in high school where we conducted experiments on statistical inference using random samples, thanks to my teacher's creative setup. The classroom featured a massive wooden bowl filled with 10,000 marbles of various colors, along with paddles boasting different numbers of holes. I desperately sought out a purchaseable set online to help teach my kids the formulas involved, but was left empty-handed. Consequently, I decided to assemble one myself. This is the 100-sample paddle I created, and I plan to make other sizes in the future. The model specifically works with beads or marbles that are exactly 8mm in diameter.
