The accepted value of a length measurement is 200cm, and the experimental value is 198cm. Circle the letter of the value that shows the precent error of this measuerment.

a)2%

b)-2%

c)1%

d)-1%

is it b)-2%

No. What is 2/200 * 100?

Percent error = deviation/GAAT * 100

gAAT generally accepted as true. Now watch signs...deviation = measured - GAAT
