A group of precise measurements are a group of repetitive measurements that are very close together. Ie the standard deviation between the measurements is small. Not to be confused with a accurate measurement! Think about it like this, if you measure a piece of wood 5 times and each time you get an identical answer then the measurement are said to be precise. If however if turns out that despite measuring the length 5 times and getting the same answer you discover that the length is significantly off from the "true" answer, then you were inaccurate!

What determines the precision of a calculated result based on measurements?
The precision of a calculated result based on measurements is determined by the precision of the measurements themselves. The more precise the individual measurements are, the more precise the calculated result will be. Additionally, the number of significant figures in the measurements and the mathematical operations involved also affect the final precision of the result.
Should conclusions to experiments be based on precise measurements?
Yes, conclusions to experiments should be based on precise measurements to ensure accuracy and reliability of the results. Precise measurements help to reduce errors and provide a clear understanding of the data collected, leading to more valid conclusions.
How does the Percision of measurements affect the precision of science calculations?
The precision of measurements affects the precision of scientific calculations by influencing the accuracy of the final result. More precise measurements lead to more accurate calculations as there is less uncertainty or variation in the data used for analysis. In contrast, less precise measurements can introduce errors and inaccuracies into the calculations.
Why is it possible for data to be precise but inaccurate?
Data can be precise but inaccurate because precision refers to the level of detail and consistency in measurements, while accuracy relates to how close those measurements are to the true value. It is possible for precise data points to be consistently incorrect, leading to inaccuracies despite the level of precision.
Which is more precise a graduated cylinder or a breaker?
A graduated cylinder is typically more precise than a beaker because it has measurement markings with smaller increments, allowing for more accurate volume readings. Beakers are generally used more for approximate measurements and mixing rather than precise volume measurements.
Why would it be important for your lab results to be both accurate and precise?
A group of precise measurements are a group of repetitive measurements that are very close together. Ie the standard deviation between the measurements is small. Not to be confused with a accurate measurement! Think about it like this, if you measure a piece of wood 5 times and each time you get an identical answer then the measurement are said to be precise. If however if turns out that despite measuring the length 5 times and getting the same answer you discover that the length is significantly off from the "true" answer, then you were inaccurate!
Why is 8.1956 most precise measuring device?
It is not; there are more precise measurements.
Which two measurements are the most prrecise?
Radio-Telescope measurements are the most precise
Can a measurements be both precise and accurate?
yes...
What determines the precision of a calculated result based on measurements?

What is the meaning of this sentence they observed precise measurements in constructing pyramids?
It means they (the builders, or architects) possessed/had very precise(exact) measurements when they were constructing (building) the pyramids.
What is the most precise measurment 6cm or 2.5cm?
2.5cm is the most precise measurement of the two measurements.
How precise are measurements to instruments?
They depend on the design of the instrument.
Is it true that an answer is as precise as the most precise measurement from which it was calculated?
Yes, the precision of an answer depends on the precision of the measurements used in the calculation. The number of significant figures in the answer should match the least number of significant figures in the measurements.
Should conclusions to experiments be based on precise measurements?
Yes, conclusions to experiments should be based on precise measurements to ensure accuracy and reliability of the results. Precise measurements help to reduce errors and provide a clear understanding of the data collected, leading to more valid conclusions.
Why are the stopwatch measurements not precise?
The measurements are not as precise as they could be because many peoples' response times are of the order of a tenth of a second. This makes it pointless to have a stopwatch recording times to a hundredth of a second.
Are precise measurements always accurate?
No. A broken clock gives a very precise time, but most of the time it is wrong.
