Tom has a meter stick which is marked off in centimeters (cm). He measures a distance three (3) times and gets measurements of: 11.52m, 11.51m, and 11.51m. A later calibration of the stick
shows it to be actually 1.001m long (1mm too long). Tom's friend Bill also has a meter stick but
it's marked off in millimeters (mm). He measures the same distance three times also, and gets:
11.452m, 11.451m, and 11.451m. A later calibration of his stick shows it to be 1.05m long (5 cm
too long)
