This is a two step problem:
First you must find the Greatest Possible Error (GPE)?
To find the greates possible error, you must acknowledge the significant place value.
In this case because it is measured to 3cm the answer is 1cm.
The GPE is half of 1cm which is 0.5cm.
Second the percent of error is a ratio of the GPE/Original measurement.
In this case it is 0.5/3 is 0.16666666667 therefore the answer is:
approximately 16.67% or 16.7% or 17%

What is the percentage error of a length measurement of 0.229 cm if the correct value is 0.225 cm?
What is the percent error of a estimated measurement of 0.229 cm if the actual value is 0.225 cm?
What is the greatest possible error for the measurement 4.7 cm?
If the number of significant digits is correct, this measurement should be between 4.6 and 4.8 and thus have a possible maximum error of 0.1.
What is the greatest possible error for each measurement. 953 mi?
It is 0.5 mi.
What shows you how accurate to the true value an experimental value is?
The error, which can be measured in a number of different ways. Error, percentage error, mean absolute deviation, standardised error, standard deviation, variance are some measures that can be used.
How do you find greatest possible error for measurement of 18.3 m?
It is half the place value of the last digit that is given. In this case, it is + or -0.05m = + or - 5 cm.
IF The weight of a rock is measured at 2.5 pounds what is the percent error in this measurement?
It depends on the calibration of the instrument you are measuring with.
What are percent errors?
A percentage error for a measurement is 100*(True Value - Measured Value)/True Value.
If percent error in measurement of mass is 3 percent and percent error in measurement of velocity is 4 percent then what will the percentage error in measurement of kinetic energy?
Kinetic Energy = 1/2 (mass) (velocity)2Measurement of mass is in error by 3%.Measurement of velocity is in error by 4%.If both are low, then KE is measured as(True KE) x (.97) x (.96)2 = 0.894 TKE = 10.6% low.If both are high, then KE is measured as(True KE) x (1.03) x (1.04)2 = 1.114 TKE = 11.4% high.If one is high and the other low, then the net error is in between these limits.
What is the percent error of the measurement 4 cm?
Percent error is calculated by the measured value and the acceped value. For example, if you measure a piece of paper and decide it is 8.45in long, that is your measured value. The package says it is 8.5in long, so it is the accepted value. The formula for percent error is |measured value - accepted value| divided by accepted value ALL times 100.
Which property of a measurement is best estimated from the percent error?
Measurement error: obviously!
Percent error formula?
Divide the calculated or estimated error by the magnitude of the measurement. Take the absolute value of the result, that is, if it is negative, convert to positive. This would make the percent error = | error / measurement |.
A student measured the mass of a small object and found it to be 56.0 grams The object's mass is known to be 55.0 grams What is the percent of error in the student's measurement?
1.8%
A student measured the mass of an object and found it to be 658 grams. The actual objects mass is known to be 755 grams what is the percent error of the measurement?
It is approx 12.8%.
How do accuracy and precision of measurement affect calculated values and percent error?
The more precise your instruments of measurement are, the less percentage of error you will have.
What does your value of relative error mean?
The relative error measurements indicates the quality of a measurement relative to the quantity of the object being measured. To derive the relative error, divide the absolute error by the value of the object being measured.
What is the formula for percent error?
The formula of percent error ispercent error= Your value/accepted value x 100------------The definition of error is: difference between the accepted true value and the measured value of a quantity or parameter. But this is the absolute error.The relative (percent error) is:(measured value - accepted true value) . 100/accepted true valueThis value is exprssed as a percentage - %.
How do you calculate percentage error for density of pennies?
Percent error refers to the percentage difference between a measured value and an accepted value. To calculate the percentage error for density of pennies, the formula is given as: percent error = [(measured value - accepted value) / accepted value] x 100.
