Observed Value True Value RelatedPercentage Calculator | Scientific Calculator | Statistics Calculator In the real world, the data measured or used is normally different from the true value. Percent difference: Percent difference is used when you are comparing your result to another experimental result. Incomplete definition (may be systematic or random) - One reason that it is impossible to make exact measurements is that the measurement is not always clearly defined. 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 see this
