Furnace temperature data

A manufacturing engineer wants to understand the sources of variability in the manufacture of glass jars. The engineer's company manufactures the glass jars at four locations. Four operators measure furnace temperatures in three batches over four shifts from the four locations.

You can use this data to demonstrate Fully Nested ANOVA.
