precision and accuracy are defined terms in science.
Accuracy is the closeness of a given result to the true value of a measurement. Precision of a result is represented by the scatter of a number of measurements.
True value is the average of a number of careful measurements by different experimenters, using different measuring systems. (consider the height of a mountain for example.)
Resolution is merely the number of digits in the answer, and of which several may be meaningless.

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!
Are precise measurements always accurate?
No. A broken clock gives a very precise time, but most of the time it is wrong.
What three steps can you take to ensure that measurements are both accurate and precise?
you can predict
Which is an example of how mathematics may be used in the collection or evaluation of data?
Mathematics can be used to complete precise measurements that can be easily presented and evaluated in mathematical form.
Is 0.25ml the same as 0.2ml?
No, 0.25ml is not the same as 0.2ml. The difference between the two measurements is 0.05ml. In terms of volume, this may seem small but in certain contexts, such as precise medical dosages or laboratory measurements, this variance can be significant. It is important to be accurate and precise when dealing with such small measurements to ensure proper outcomes.
Can a measurements be both precise and accurate?
yes...
What provides a more accurate description of matter than measurements?
There is no more accurate descriptions of matter than measurements. To get the description right make your measurements precise.
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!
A measurement that is accurate is one that?
The measurement that is accurate is one that is precise. These are also commonly titled accurate measurements in the books.
Explain how a series of measurements can be precise without being accurate?
yes
Can a flask perform accurate measurements?
Flasks are not typically used for accurate measurements as they lack precise volume markings. For accurate measurements, graduated cylinders or volumetric flasks are commonly used due to their precise volume markings.
Are precise measurements always accurate?
No. A broken clock gives a very precise time, but most of the time it is wrong.

Is it possible for an observation to be accurate but not precise?
Yes, it is possible. Accuracy refers to how close an observation is to the true value, while precision refers to how close repeated measurements are to each other. An observation can be accurate if it is close to the true value, even if the measurements are not precise and vary widely.
