A error in measurement is when the measurement taken is not actually correct. For instance, you measure a gap as 49 centimetres wide. You cut the plank of wood to fit that measurement. Then discover the wood you have just cut is too wide to neatly fit the gap. There has been an error in the measurement you have taken.
What else can I help you with?
Which property of a measurement is best estimated from the percent error?
Measurement error: obviously!
If a measurement is small is the percentage error high?
yes, it is. The smaller the measurement, the higher the percentage error.
What are the two factors affects accurate measurement?
Calibration error and measurement error. Also, if the measurements are of different objects there may be random error.
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 determines how close a measurement is to the true or accepted value?
This value is variable and different for each type of measurement. The error can be absolute or relative. A measurement without any error doesn't exist.

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 |.
How to calculate the standard error of measurement?
To calculate the standard error of measurement, you can use the formula: SEM SD (1 - reliability). SEM stands for standard error of measurement, SD is the standard deviation of the test scores, and reliability is the reliability coefficient of the test. This formula helps estimate the amount of error in a test score measurement.

The purpose and function of standard error of measurement?
the purpose and function of standard error of mean
What is the size of error for a measurement ranging from 0 to 3?
The absolute error can be as large as 1.5
If error in the measurement of momentum of a particle is 100 percent then the error in the measurement of kinetic energy is what?
p=mv %errror in p= %error in m+%error in v lowest value of m=0 hence %error in velocity=100% k.e=%error in mass=2*%error in velocity K.E=200% similarly K.Eminimun=100% total error in K.E = 100+200 =300 hence error in ke = 300%
What is the value of relative error if the absolute error is 10?
The relative error depends on the true value of the measurement. That information has not been provided.
Source of error in measurement?
Some common sources of error in measurement include human error such as misreading instruments or recording data incorrectly, instrument error like calibration issues or sensor drift, environmental conditions affecting measurements, and systematic errors inherent to the measurement method itself.
