What is Limit of precision?
The precision of something just means that the result can be repeated again and again. Everytime you repeat an experiment, you will get the same result. But that doesn't necessarily mean that the results are accurate! Your measurments, results, whatever can be very precise, but completely inaccurate. Accuracy is how close something is to the true value. For example, say I have a ruler. I have used this ruler to measure my table 10 times. Every time I measure the table, I get a measurement of 10ft. My measurement is very precise. However, what I don't know is that there is a fault with my ruler. The inches on my ruler are not true inches. Each inch may actually be only 1/9th of an inch. Or all the inches on my ruler may not even be the same. So while my measurements I took with my ruler 10 times are precise, they are not accurate because there is fault with my ruler. Something can be precise, but not necessarily accurate! I would say that this is the biggest limitation of precision. A precise measurement is not always a reliable one!
What does the term OHM mean?
It is a unit of measurement to measure the resistance an object possesses when electricity flows through it.
What does it mean to weigh accurately about 1.0 gram of something?
This is a lesson in significant figures and the importance of knowing what those significant figures represent. To measure out 1.0 grams of a substance, you need to weigh out between 1.05 and 1.14 grams of the substance. This is much more precise than weighing out 1 gram of a substance, which could be anything from 0.50 to 1.49 grams. The addition of the zero after the decimal point makes the measurement much more precise.
If a graduated cylinder was not correctly calibrated how would it affect the results of a measurement?
This is one of those oddly obvious questions. If a graduated cylinder was not correctly calibrated, then it would yield an incorrect meaurement when you use it. Withouth calibration, you wouldn't know if it was reading high or low. It might be possible to make precise measurements, but precision is a different quality from accuracy. Being able to measure to a tenth or hundredth of a mililiter doesn't mean much is your measurement is off by half a mililiter.
What would be used if you were measuring the length of something in meters of inches?
There is no such measurement. There is either metric measurement or not. Do you mean "fractions" of inches?
Can a measurement be precise without being accurate?
You can make a very precise measurement with a poorly calibrated device.
Is 42.3 ounce more precise than 35.6 tons?
Unfortunately, there is not a simple answer: it depends on what you mean by "more precise". Both have three significant figures and to that extend they are equally precise. However, the maximum possible percentage errors in the two measurements are approximately 100*0.05/42.3 = 0.12% and 100*0.05/35.6 = 0.14%, respectively. On that basis, 42.3 ounces is more precise in relative terms. Also, the measurement units are smaller for 42.3 ounces so in absolute terms the measurement is more precise.
What does it mean to round to the least precise measurement?
Round to whatever non-zero digit is farthest to the left.
Explain why is a highly precise measurement doesn't not always mean a highly accurate one?
Accurate means how close the measured value is to the real, actual value. Precise means how reproducible the measurement is. So, if the real value is 1.00, and you measure it to be 0.785, and every time you measure it, it comes out the same (0.785), then the measurement is VERY precise, but not very accurate.
What does rse 825 stamp mean on earring?
I do not know 825 but RSE The relative standard error (RSE) is a measure of the reliability of a survey statistic. The smaller the relative standard error, the more precise the estimate.
How can you tell how accurate a measurement is?
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.
What one what words means the degree to which a measurement is precise and reliable is it variable or accuracy or parameter or constant?
-- None of those words relates to "precise". -- "Accuracy" relates to "reliable". -- "Precision" and "accuracy" are two different things. -- "Precise" does not mean "reliable".
How do you measure mean length?
You measure a great number of them, keeping records of every measurement, and then you calculate the average of all of the measurements.

What does the word estimation mean?
It means to guess at something. An imprecise amount or measurement.
What does inched means?
It doesn't mean anything. It is simply a unit of measure.
What does barleycorn mean in units of measurement?
It is an obsolete unit of measure, equal to one third of an inch.
