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.
Why are several trials taken for each measurement in an experiment?
A good way to reduce error or increase measurement accuracy is to take several measurements and compute their average. In other words, you achieve accuracy through averaging. (This also validates the repeatability of the measurement.)
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 can reduce the percentage error?
The larger the sample, the lower the % error.. so to reduce a % error, increase your sample size.
How does a scientist reduce the frequency of human error and minimize a lack of accuracy?
take repeated measurement
Is every measurement subject to errors?
Yes. There is no system of measurement that is "perfect" in every way. We work hard to reduce error or uncertainty when we measure stuff, but we cannot eliminate it.

What is an error in measurement?
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.
How do you reduce systematic error?
Systematic error is the result of complete equilibrium. The method to reduce systematic error is to introduce a proof that demonstrates the group has error in their consensus.
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 do you overcome or reduce the problem of random error and systematic error while doing an experiment?

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.
