Επιλέξτε τη What Is A Good Percent Error What is your percent error?Solution: experimental value = 8.78 g/cm3 accepted value = 8.96 g/cm3Step 1: Subtract the accepted value from the experimental value.8.96 g/cm3 - 8.78 g/cm3 = -0.18 g/cm3Step 2: Take

Since the experimental value is smaller than the accepted value it should be a negative error. For example, for a thermometer reading 43 °C, if it is not of high quality the real temperature could be as high as 44 °C or as low as 42 °C.
