To check the precision of an instrument its apparent measurement must be compared to a known measurement. The difference between the measured quantity divided by the known quantity is expressed as a % precision of the instrument, or calibration. Most instruments when being calibrated are tested against multiple known quantities throughout the range of the instrument. Thus the precision of the instrument is determined throughout it's full range of measurement.
You can use a tool that has a smaller amount of uncertainty. An amount of uncertainty is how "small" a unit the tool can measure in. For example, a meter stick usually has marks up to the millimeters. There is something called a micrometer [where I live, anyways], which can measure up to .1 of a millimeter. Thus, micrometers can get more precise measurements in comparison to a meter stick.
you can make an experiment more precise by the equipment which you use:
Compare reading against a calibrated item. There are calibration instruments and procedures for all measuring devices. Basically, these allow comparisons to known, and very well maintained, standards, usually in an indirect fashion.
You can tell how accurate a measurement is by comparing it with the accepted?ævalue. The accuracy can be obtained using the mean absolute percentage error formula.
Only by changing the method used to take the measurement, which could include changing the person performing the measurement.
practice, practice, practice or redo it many times. It happens to me a lot at school. Don't get frustrated either.
The measurement that is accurate is one that is precise. These are also commonly titled accurate measurements in the books.
It uses smaller segments of measurement making it more accurate
A measurement that can be repeated by an independent person or team of investigators.A measurement that includes the margin of error and resolution of the measuring equipment.
Imagine a dartboard. An accurate measurement would be analogous to hitting the bulls-eye. While a precise measurement is just the tight clustering of shots.
The glassware that provides the most accurate measurement of volume is the measuring cup. A glass measuring cup has lines on it to give an accurate reading.

no
For more accurate readings of measurement.
What determines how precise a measurement is
The Seismic Moment Scale is the most accurate measurement of an earthquake's magnitude.
accurate body measurement is important to insure the dress you will wear or buy is fit to you
height measurement is the accurate and dependable measurement for a man, object or anything.
The smaller the unit the more accurate the measurement will be.
An automatically measurement has a higher precision than a manually measurement.
No. The early systems of measurement were not as accurate as those I use today. The systems of measurement I use today are substantially more accurate than the early systems of bygone days were.
The engine most NOT be running for accurate motor oil measurement. The most accurate measurement is when the car has not been running for at least a few hours and is sitting on level ground
Accuracy is the tendency for a measurement to be correct. A more accurate measurement will be closer to the true value than a less accurate measurement. Precision is the tendency to come to the same measurement under the same conditions on multiple occasions. A precise measurement may not be accurate, but can be reproduced time after time and give the same (or sImilar) result.
