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, which may be purchased seperately. 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.
