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.
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.

Quantitative observation is a type of observation that involves measuring or counting a specific characteristic or property of an object or phenomenon. It focuses on numerical data or information that can be quantified and compared. This type of observation is especially useful in scientific research to gather precise and measurable data.
Yes, a measurement can be precise without being accurate. Precision refers to how close repeated measurements are to each other, while accuracy refers to how close a measurement is to the true value. It is possible for measurements to be consistently close to each other (precise) but consistently off from the true value (inaccurate).
Inaccurate observations can lead to false conclusions and misinterpretation of data, hindering the progress of scientific inquiry. To ensure the reliability and validity of scientific research, accurate and precise observations are necessary to form the basis of sound conclusions and theories. Mistakes or biases in observation can distort results and impede the advancement of knowledge in the scientific field.

no only if it is precise it is accurate
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.
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.
precise means accurate
What determines how precise a measurement is
The correct spelling is 'precise mechanics.' 'Precise' means exact or accurate, so precise mechanics refers to detailed and accurate mechanics in a specific context.
Precise.
Accurate or precise are one and the same to which the automotive speedometer would never be.
Cause if it isn't accurate u don't get more details
yes...
Precise or Exact.
