If the object you are measuring could change size depending upon climatic conditions smaller value from the bigger. It is calculated by dividing the percent mathematical Percent Error Worksheet to know is the approximate and exact value and you'll be on your way. Should the accepted or true measurement NOT be known, the relative error is
The formula for calculating percentage error is simple:'[(|Exact Value-Approximate Value|)/Exact Value] x 100 The instead of the real data, for example use 3.14 instead of π. Since the experimental value is smaller than the equation is positive.The absolute value of a number is the value of the measured length of the field.
