SBL-2000 Sampling Bowl

SBL-2000 Sampling Bowl

The first sampling bowl was used by Walter Shewhart (inventor of the control chart) back in the 1920''s. He used an old kitchen mixing bowl for teaching statistical principles. Our modern Sampling Bowl is handsomely constructed of Lucite and measures 14" x 11½" x 9" deep and includes three sampling paddles with 25, 50, and 100 hole patterns.

The bowl also comes with 1800 white, 400 red, 100 yellow, 100 green, 100 black, and 100 blue beads. Extra beads may be purchased with any sampling bowl order. The Sampling Bowls most popular use is the Deming red bead experiment as described in Chapter 4 of The Deming Dimension. A complete set of instructions is included with each sampling device.

It is also effective for teaching attribute control charts, probability theory, acceptance sampling, and developing OC curves. Like the Quincunx, applications are only limited by the imagination of the instructor.
