take reading 4 to 5 times, and take its average
this will reduce error
Measurement error: obviously!
yes, it is. The smaller the measurement, the higher the percentage error.
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.)
Calibration error and measurement error. Also, if the measurements are of different objects there may be random error.
The larger the sample, the lower the % error.. so to reduce a % error, increase your sample size.

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.
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 |.
Yes, every measurement is subject to errors due to various factors such as limitations of the measuring instrument, human error, environmental conditions, and inherent variability in the quantity being measured. It is important to acknowledge and account for these errors to ensure the accuracy and reliability of the 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.
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.
The more precise your instruments of measurement are, the less percentage of error you will have.
