The most any measurement can be off by is HALF the unit used in measuring.
Therefore, if you measured in inches the "possible error" is a half inch (.5 in.).
If you measured to the nearest quarter of an inch (1/4 in.), then the "possible error" is one­eighth of a quarter of an inch (1/8 in.). possible error = .25 x .5 = .125 .125 = 1/8
The minimum or maximum possible values = measured value + or ­ possible error

FINDING GREATEST POSSIBLE PERCENT ERROR
1. Calculate possible error
2. Calculate measured volume
3. Calculate minimum volume
4. Calculate maximum volume
5. Calculate greatest difference from measured volume
6. Use the greater difference to find the greatest possible percent error
Greatest possible percent error = greater difference in volume
measured volume
