MATRIX          18     4
) This is an experiment to determine how sample, temperature,
) and rpm affect viscosity of processed cheese.  Two random
) samples of process cheese are obtained, and each is divided
) into nine cubes.  These cubes are then randomly assigned to
) the nine factor/level combinations of heating temperature
) (80, 85, and 90 C) and rpm (100, 200, and 300).  Cubes are
) tested in random order by heating the cube to its assigned
) temperature (with 1 ml of propolyene glycol) and then measuring
) the apparent viscosity at the assigned rpm.  
) The columns below are sample, temperature, rpm, and response.
) Data from Lisa Leman.
