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 The result of the difference is positive and therefore the percent error is positive. The circumference of a circle is given by pd. Reply ↓ Mary Andrews February 27, 2016 at 5:39 pm Percent error is always represented as a positive value. navigate here

Did you mean ? The error in judging the reading is therefore bigger that the error from the stop clock.

What Is A Good Percent Error If this is realised after the experimental work is done, it can be taken into account in any calculations.

Note that decimal points have nothing to do with significant figure.

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. his comment is here A systematic error is one that is repeated in each measurement taken.

Figures that are not significant should not be included in a calculated value. Percent Error Worksheet Since the experimental value is smaller than the accepted value it should be a negative error. Now get out a calculator.

There is an experimental uncertainty (often called 'experimental error').

The human reaction times can vary and but I estimate around ±0.1s. Thanks. Started by: saraxh Forum: Chat Replies: 55 Last post: 1 Hour Ago Pm? Percent Error Chemistry Definition Example: You measure the plant to be 80 cm high (to the nearest cm) This means you could be up to 0.5 cm wrong (the plant could be between 79.5 and

This will give you a decimal number. Convert the decimal number into a percentage by multiplying it by 100. Add a percent or % symbol to report your percent error value.Percent Error Example Reply tammy-04 Follow 0 followers 0 badges Offline 0 ReputationRep: Follow 8 06-05-2011 23:54 (Original post by Phalange) How did you get your answers? The difference between the actual and experimental value is always the absolute value of the difference. |Experimental-Actual|/Actualx100 so it doesn't matter how you subtract. http://setiweb.org/percent-error/percent-error-chemistry-formula.php If a number of different people carry out the same measuring procedure and the values are close the procedure is reproducible.
