SCB-7 Shewhart Chip Box
The Chip Box is an effective teaching aid for demonstrating the
use of samples to make estimates about populations. The device
consists of a box with a series of numbered chips whose numbers
are normally distributed.
Sampling from a normal distribution is simulated by randomly selecting chips and recording the results. The effect of varying sample sizes on predicting population parameters is dramatized by repeating a number a experiments as described in Chapter Two of Grant and Leavenworth's book Statistical Quality Control. This book is not included with the chip box. It can be purchased through Amazon.com at http://www.amazon.com/Statistical-McGraw-Hill-Industrial-Engineering-Management/dp/0078443547/ref=pd_bbs_3?ie=UTF8&s=books&qid=1203000705&sr=8-3
The Chip Box is made of highly polished ½ inch Lucite measuring 6" x 6" x 8" and contains 802 numbered chips in four colors. The Chip Box adds that professional touch to any statistics class.
