Name: Tablets


Abstract: The quality engineer checked the thickness and hardness of 60 tablets (randomly chosen) that the pharmaceutical company produced.  Tablets were to be within 2.5-4.5kb (hardness) and .105-.135in (thickness).


Variables (column):

  1. Tablet Number (1-60)
  2. Hardness required to break the tablet (kilograms of pressure (kp))
  3. Thickness (inches)


Possible Uses: Correlation
