What else can I help you with?
Is a refers to how close a measurement is to the true or accepted value?
Accuracy.
Factors affecting accuracy and precision in measurement?
Factors affecting accuracy in measurement include calibration of instruments, human error, and environmental conditions. Factors affecting precision include repeatability of measurements, instrument resolution, and presence of systematic errors. Regular calibration, training of personnel, and controlling environmental conditions can help improve both accuracy and precision in measurements.
When you perform an experiment it is important that measurements are accurate.what determines the acuracy of a mesurment?
The accuracy of a measurement is determined by how closely the measured value corresponds to the true value of the quantity being measured. Factors that can affect accuracy include the precision of the measuring tool, human error, calibration of instruments, and systematic errors in the measurement process.
How zero error affect accuracy?
Zero error can negatively affect accuracy by introducing a consistent bias in measurements. This bias can lead to all measurements being systematically shifted in the same direction, resulting in incorrect readings. It is important to account for and correct zero error to ensure the accuracy of measurements.
Different between precision and non precision instrument?
Precision instruments provide accurate measurements with low margins of error, while non-precision instruments offer less accurate results with higher margins of error. Precision instruments are designed for tasks that require high accuracy, such as scientific research and engineering, while non-precision instruments are suitable for rough estimations or general use where high accuracy is not critical.
What is the difference between accuracy and presicion?
Accuracy is a measure of how close to an absolute standard a measurement is made, while precision is a measure of the resolution of the measurement. Accuracy is calibration, and inaccuracy is systematic error. Precision, again, is resolution, and is a source of random error.
Is accuracy or precision related to standard error?
Standard error is a measure of precision.
How do accuracy and precision of measurement affect calculated values and percent error?
The more precise your instruments of measurement are, the less percentage of error you will have.

Define accuracy and precision?
Accuracy and precision are synonyms. They both mean without error, they are exactly right, No more and no less.

How can a series of measurements be precise without being accurate?
Precision is the number of significant figures, a function of the instrument / procedure used. Accuracy describes measurement error, indicating how closely that the measurement represents the actual value. Errors affect accuracy... like the butcher's thumb on the scale.
Is accuracy a measure of how close an answer is to the actual or expected value?
Precision and accuracy are two ways that scientists think about error. Accuracy refers to how close a measurement is to the true or accepted value. Precision refers to how close measurements of the same item are to each other. Precision is independent of accuracy.
How are accuracy and precision important?
Accuracy is whether or not the average of all of the trials in a specific experiment is equal to the intended amount--it may have been given to you or you may have to do some calculations to determine the correct amount. Accuracy is important in an experiment so one can come up with the correct answer. One one to deter from having accurate measurements is having random or systematic errors (random=fault on experimenter's behalf, systematic=error in calibration of an istrument). Precision, on the other hand, entails the reproducibility of an experiment. This just means that all trial results were fairly close to each other. This does not necessarily mean the experiment was accurate, however, as precise measurements can be all close to each other but far away from the intended result. This could be the result of a systematic error. Accuracy and precision are both important to have in an experiment as it ensures both a correct result and reproducibility.
What is the systematic error detection?
Systematic error detection is the process of identifying and correcting consistent errors or biases in data collection, measurement, or analysis. This helps ensure the reliability and accuracy of results by addressing any recurring issues that may affect the validity of the findings. Common techniques for detecting systematic errors include using control groups, calibrating instruments, and conducting multiple trials.
