Description:

The data come from Nambe Mills, manufacturers of tableware made from sand casting a special alloy of several metals. The polishing times for the products are thought to be related to the size of the item, as indicated by the diameter. After casting, the pieces go through a series of shaping, grinding, buffing, and polishing steps. In 1989 the company began a program to rationalize its production schedule of some 100 items in its tableware line. The total grinding and polishing times listed here were a major output of this program.

There are 59 observations on four variables.

Variables:

Type	The type of product: either a bowl (Bowl), a dish (Dish), a tray Tray), a plate (Plate) or a casserole dish (CassDish).
Diam	The diameter of the product in inches.
Time	The grinding and polishing times in minutes.
Price	The price in $US.

Data Quality:

There are no missing values.

Source:

The data are originally from the Name Mills company, as quoted as the DASL website.

Notes:

The interest in collecting the data was to find a model for the polishing and grinding times. Price could also be modelled.
