What is one thing scientists do to make sure their measurements are precise and accurate?

There is no single answer and the answers depend on the context.
Normally scientists will take multiple measurements with different instruments so that errors should average out. However, that may not be feasible for very rare events. In that case they need to calibrate their instruments extremely carefully. They also need to ensure that the effects of external factors (eg vibrations from traffic going along the road outside the lab, or gamma radiation from space) are minimised or can be eliminated (by shielding) or accounted for (in calculations).

Is one fourth twenty five percent?
Yes. Generally scientists use fractions because they are more accurate then numbers 1/4=25%=0.25=4/16 they're all the same thing.
What is 686 cc converted to mph?
The question that you have do asked is, I'm afraid to say, not possible. The two measurements that you have asked about do not measure the same thing. "cc" stands for cubic capacity. It measures capacity. It measures the same as litres. "Mph" measures speed. The two measurements are not interchangeable. Furthermore, one is a metric measurement and one is imperial. They are measurements from different eras of recent history.
.5L what is the difference 16.9 fl oz?
.5 L = 16.9070114 US fluid ounces. So, technically .0070114 fl oz, but for most purposes that do not require a very, very, very, precise measurement, like chemistry, they are basically the same thing.
Does a set of all sets contain itself?
There is no such thing as a "set of all sets". To be more precise, the idea of a "set of all sets" leads to contradictions; therefore this term is avoided in set theory. Check the Wikipedia article on "Universal set" for more details.
If the area of a rectangle is 11.5 square meters what are the dimensions?
You can't tell. The area doesn't tell you the dimensions. There are an infinite number of possible pairs of length/width measurements. The only thing you know for sure is that whatever the length and width are, you get 11.5 when you multiply them.
What is a word that means the same thing as scientific?
Systematic, exact, accurate, clear, controlled, precise, sound, methodical, deductive, logical, experimental...
Is it possible to get a precise measurement that is not accurate?
Certainly. Precision and accuracy do not mean quite the same thing. All measuring tools need to be recalibrated from time to time against a standard. For instance you can get a very precise reading from a micrometer or vernier gage but if it has not been correctly calibrated the reading will not be accurate.
How would you collect accurate and precise nest data?
well, im trying to figure out the same thing but with the American Crocodile [sorry i cant answer your qustion].

What is a precise measurment?
A precise measurement is an exact measurement.How long,how tall how wide. EXAMPLE-12X5X24Precision refers how close measurements of the same thing are to each other. A precise measurement is one that is similar or the same as previous measurements. A precise measurement does not need to be accurate.precise measurements may not be accurate but will agree with each other. Characteristic of precision is low standard deviation. It is not in all cases proof of accuracy though
Is this thing accurate?
It depends on what thing you are pointing to.
Why do scientists need to know which digits are signifcant?
*Chemistry example* Chemists/scientists need to know which digits are significant because when measuring thing such as mass, your scale may have only 3 significant digits. If you are trying to find the moles, you can only use 3 sig figs in your answer because any more are not precise.
Why do scientists publish their findings?
to help other scientists who are stuck on the same thing

What are the advantages of using the tlm 300 distance measurer over a tape measure?
well for one thing it measures distances that are far longer than a tape measure could ever stretch. 200metres to be precise and some of these other reasons: · It has a Pythagoras function for remote measurement of high walls. · It can measure distances up to 200m which the tape measure cannot. · It has min-max, tracking and trapezoid measurement for accurate layout. · It has memory and history recall. · It has a rapid and precise one person operation over long distances. · It is easy for it to take measurements in busy or out-of-reach areas. · It has calculator functions for quick and easy area, volume and other measurement. · It has a timer function. · A one person operation means greater productivity. · Level ensures measurements are extremely accurate. · It has a fitting for a camera tripod. hope this info is good enough im doing a project on it as well so that's how i know all this byeeeeeeeee:)
When will Britain do the decent thing and change its road signs to metric measurements?
never they say they will when every one is used to metric measurements
Why do scientists classify fish?
Because that's the kind of thing scientists do. They figure things out, sort them up in an orderly manner. Who's related to who, that kind of thing.
