A measurement can be precise without being accurate?

You can make a very precise measurement with a poorly calibrated device.


Is it possible to make exact measurements?

It is according to the measurement markings on the instrument. If there are many, it is more likely to be exact or accurate. Also it depends on if you started on the very center of the very first marking, and did not move the instrument while measuring. So, the answer is ... yes.


How can the precision of a measuring instrument be increased?

Make sure you are only measuring what you are after. Not noise and local disterbances. Proper system grounding is needed. Make sure the device you are using has been calibrated periodically properly to a N.B.S. standard. Your measurement will only be accurate to 10 times the standards value. That is a 0.3% accurate standard will only give you a 3% accuracy in your measurement.

Why are repeated trials of the same measurement desirable?

Repeated trials of the same measurement will show validity, IF the measurement is a valid measurement. For example, most psychological tests administered by professionals have been validated. But, if a person tried to make up questions similar to the MMPI test, the made up questions would only be an unscientific poll and would not be a reliable instrument.


When is a measurement accurate?

Never: A measurement made is always an approximation. We can get very close to being accurate with our measurements, but never fully 100% accurate. This is not the fault of the person measuring, or what tool they are using to measure with, but it is a natural law that we (anyone, even superior aliens to humans) cannot ever fully make an absolutely accurate measurement.

Why do scientists repeat the same measurement several times?

to make sure their test results are accurate


Why might scientists make a measurement more than one time?

They want to check that it is accurate.
