Psyc 227 Introduction to Statistics Dr. Fairchild True Limits and Midpoints True Limits of a Number or Interval: Think of weighing yourself on the bathroom scale that only marks off whole pounds.  Suppose you look down at the needle, which is in between 124 and 125 pounds, but  closer to the 125 mark. If you are being brutally honest with yourself, you say that you  weigh 125 pounds. Now imagine that you look down at the needle and it is between 125  and 126 pounds, but closer to the 125 mark. Again you would say that you weigh 125  pounds. What you are doing is indicating that any weight between 124.5 and 125.5 is  treated as 125 pounds. Thus, for the number 125, we say that the true limits of the  number are 124.5 and 125.5.   125 124.5
