How do you keep your measurements consistent even if you are not precise or accurate?

You could do it by saying that all your measurements were 10 centimetres - irrespective of what they actually were. That would be neither precise nor accurate but it sure would be consistent!

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 is the difference with precision and accuracy?
Accuracy refers to how close a measured value is to an excepted value. Precision refers to how close a series of measurements are to one another For example, if your experimental value is 15.63 and your values are... 12.84 13.02 12.96 They would be precise because they are close to one another but not accurate because they're not even close to the experimental value
what is the difference between accuracy and precision?
''Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.
What measuring device use for size of the classromm?
A tape-measure could be used to measure a classroom. A metre length stick, or even pacing are other means that can be used. It rather depends on how accurate the measurements need to be.
Why are womens clothes size in even numbers?
Apparently, women's clothes sizes are in even numbers because of standardized measurements. When you cut cloth, you can standardize the measurements.

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 did the COBE satellite find that suggests that the big bang explosion occurred?
The CoBE (Cosmic Background Explorer) proved, beyond any doubt, that the spectrum of the CMBR is that of a black-body of temperature 2.7K -- some researchers were finding slight differences from this. The VERY minor anisotropies (about one part in 10,000) found in the CMBR are consistent with matter clumping in the early Universe, just enough to produce galaxies. Note that WMAP and the Planck Probe have done even more precise measurements, and continued to get results consistent with CoBE.
What is the prefix for precise?
-Curo is the suffix even though it is not included in the word. -Curo means to take care of.
Why should quantities of colour and developer be mixed accurately?
Accurate mixing of hair color and developer are very important in order to have even color coverage and precise, true color results.
Can measurements be accurate and not precise?
Precision is a measure of how close to each other repeated measurements are. Accuracy is how close to a target value the measurement is. The only reason this unneccessary bit of info is in your book is to cram kids' heads with useless info. Very few scientists or engineers care about this trivia. Real science is about understanding how things work.
When is a measurment 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 are polls used so often even though they aren't precise?
Even if they are not precise, they often give a good general idea.

Is link Zelda's childhood friend?
The Zelda games are not horribly consistent in terms of backstory, even though they keep using the same character names. The precise relation between Link and Zelda varies depending on which game you're talking about.
Is shoe size is discrete or continuous?
Typically measurements are continuous variables so a shoe size is a continuous variable since it can be expanded to be more precise. You can generally say that a person wears a size 8 but 7.9 or 7.934567 is more precise, even though US shoe sizes only come in whole or half sizes, you still can be more and more precise in your foot measurement or actual shoe size.
