Accuracy, precision, repeatability and so on are terms that have been closely defined for measurement purpose. By folk such as ASTM. and ISO.
The true value is the value towards which a large number of different measurements (by different measurement teams, using different measuring systems ... ..) tends.
The accuracy of a particular method or measurement is how closely that answer comes to the True Value.
The precision of a measurement represents the confidence you have in the measurement. (Generally by making several measurements.)
The resolution of a measurement is merely the number of figures in your answer. A number with many places would have greater resolution, but many of those numbers might be meaningless.
So, a single measurement of the height of a mountain for example, might be correct, (true value) but you don't necessarily have reason to be confident of the answer.

Is it possible for an observation to be accurate but not precise?
yes
Why is important for observation to be accurate?
Cause if it isn't accurate u don't get more details
What is important for observations to be accurate and carefully recorded?
Observation should be accurate so that in future it can be use correctly.
Can a measurement be precise without being accurate?
You can make a very precise measurement with a poorly calibrated device.
What is the difference between precise and accurate?
Accuracy is how close to the truth and precision is how narrow the the range of uncertainty or error. For example in guessing weight, of 150 # person, an accurate guess could be 140 # +- 15 #. An inaccurate guess would be 145# +- 2#. The first guess is accurate but not precise, the second is inaccurate but more precise.
Is it possible for an observation to be accurate but not precise?
yes
What is criminolgy of a science?
Criminology is a social science that studies the causes, consequences, and prevention of criminal behavior. It involves analyzing crime trends, patterns, and behaviors to develop theories and strategies aimed at reducing and understanding criminal activity. By incorporating elements of sociology, psychology, and law, criminology provides insights into why individuals commit crimes and how society can address these issues.
Can a number be accurate but not precise?
no only if it is precise it is accurate
Are 76.48 cm 76.47 cm and 76.59 accurate or precise?
These numbers are precise, as they are all close together. If any one of these are accurate, then this group of numbers can be considered precise and accurate.
What measurement is more precise and accurate?
What determines how precise a measurement is
Does the word precise means careless?
precise means accurate
Does a set of values mean the same as an observation?
No. One observation will normally get you onevalue, not a set of values. Also, to be precise, the observation is the act of observing; the value is the result of the observation, not the observation itself.
Which measurement is more precise 57 57.2 57.21 or 57.213?
The word accurate is a synonym for precise. So the most accurate (or precise) answer would be 57.213 because it is more accurate if the number is not rounded.
What is harder word of accurate?
Precise.
Would it be more important for your car speedometer to be accurate or precise?
Accurate or precise are one and the same to which the automotive speedometer would never be.
What is the difference between accuracy and precision and which one is more important to scientific measurement?
To be accurate is to be correct, for example, if you say it will rain tomorrow and it does rain tomorrow, then your prediction was accurate. Precision means to give a finely detailed measurement or observation, rather than an approximation. In the case of the weather prediction, a precise prediction might be on the order of, it will rain a total of 1.68 inches of rain, tomorrow. Such a prediction might or might not be accurate, but if it is, then it is also precise, much more precise than merely predicting that it will rain. Precision includes the concept of accuracy. An observation that is precise but inaccurate is useless; precision is only valuable when it is also accurate. Scientists cannot really choose between accuracy and precision since both are necessary for science to succeed, but accuracy is more fundamental. Something that is approximately correct is worth more than something that is very detailed, but wrong.
Meaning of precise?
It means-exact, specific or more accurate. example: can you be more precise on your answer?
