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
Can a measurement be precise without being accurate?
You can make a very precise measurement with a poorly calibrated device.
How do you explain how results can be precise but not accurate?
Results can be precise to the exact feat done. The results of a lab test are precise to everything that influenced, or interfered with the end result. The results of the same lab test may not be accurate for what is it being tested for.
What is the difference between Gregorian calendar and Roman calendar?
The difference is the accuracy of mathematical computation of the length of the day, in essence. The Roman calendar was fairly accurate (considering the computation tools of the time, quite accurate), but over a period of many years, it was off by a period of (then) ten days. The Gregorian calendar proposal used more precise mathematics, and deduced that the calendar had lost ten days since the calendar of Rome was established. The calendar was jumped forward ten days (it's a long story). The current (Gregorian) calendar is accurate to about one day every several thousand years.
What is the difference between a shadow formed by a point source of light and a extended source?
The shadow formed by the point source of light has a screen blocking it. So it is very precise and only forms an umbra. Whereas the other is not as precise and forms an umbra and a penumbra.
What is the difference between acurtate and precise?
An accurate answer to a question answers the question. The precision depends on the level of accuracy of the answer.
What is true if a digital scale reports a 10kg weight as weighing 8.975 kg?
The scale is precise but not accurate. (APEX)
What is the difference between an accurate and a precise measurement?
The article at the link below should help you get a handle on the subtle differences between accuracy and precision.
What is the difference between Precise and Concise?
precise is precise and concise is concise
What is a Systematic?
Systematic error is the difference between the actual value of what is being measured and the value you found. The results of systematic error are precise but not accurate.
Can a number be accurate but not precise?
no only if it is precise it is accurate
What is the systematic error detection?
Systematic error is the difference between the actual value of what is being measured and the value you found. The results of systematic error are precise but not 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 are accuracy and precision and what is the difference between accuracy and precision?
Imagine a dartboard. An accurate measurement would be analogous to hitting the bulls-eye. While a precise measurement is just the tight clustering of shots.
What measurement is more precise and accurate?
What determines how precise a measurement is
Does the word precise means careless?
precise means accurate
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.
