If you need to know positive or negative error, this is done by dropping the absolute value brackets in the formula. In most cases, absolute error is fine. A: Seliwanoff's test for carbohydrates determines if sugars are aldose sugars or ketose sugars, according to Reference.com. Absolute Error and Relative Error: Error in measurement may be represented by the actual amount of error, or by a ratio comparing the error to the size of the measurement. Solution: Given: The measured value of metal ball xo = 3.14 The true value of ball x = 3.142 Absolute error $\Delta$ x = True value - Measured value =
