Accuracy refers to how close a measured value is to the true value, while precision refers to how close multiple measured values are to each other. In an investigation, accuracy ensures that the results reflect the true nature of the phenomenon being studied, while precision ensures that the experimental data is reliable and reproducible. Both accuracy and precision are important for obtaining valid and meaningful results in research.

What determines the precision of a calculated result based on experiments?
The precision of a calculated result based on experiments is influenced by the accuracy and limitations of the measuring instruments used, the variability of the experimental conditions, and the number of data points collected. Additionally, the uncertainty associated with each measurement and the use of appropriate statistical analysis methods can also affect the precision of the final result.
Is accuracy better high or low?
Accuracy is better when it is high. High accuracy means that the measurement or result is closer to the true value or target, indicating precision and reliability. Low accuracy can result in errors and incorrect conclusions.
What determines the precision of calculated result based on measurement?
the precision of the least precise measuement
What is accuracy and precision and the difference between them?
Accuracy refers to how close a measured value is to the true value, while precision refers to the consistency of repeated measurements. In other words, accuracy is related to correctness, while precision is related to repeatability. A measurement can be precise but not accurate if the values are consistently off by a certain amount, and it can be accurate but not precise if the values vary widely with each measurement.
How does the Percision of measurements affect the precision of science calculations?
The precision of measurements affects the precision of scientific calculations by influencing the accuracy of the final result. More precise measurements lead to more accurate calculations as there is less uncertainty or variation in the data used for analysis. In contrast, less precise measurements can introduce errors and inaccuracies into the calculations.

Accuracy is a measure of how consistently a result is determined by repeated evaluations true or false?
False, that's precision.
What is an example of an archery contestant showing good precision but poor accuaracy?
Accuracy implies that there is no deviation from the desired result. Precision implies a consistent closeness to the desired result. An archery contestant whould show poor accuracy because the arrow is always off the target center. Good precision because it is always close to the target center.

Differentiate accurate from precise in measurement?
Accuracy is when the result is close or equal to the actual value or expected result. Precision is when multiple results are within the same or very close value. With multiple results, you can have accuracy and precision if the results are on target, and all within a very close range. However, if the results have quite a bit of deviation among them, but the average result is on target, then you have accuracy, but low precision. If multiple results are way off target, but are all within a close range of each other, then you have low accuracy and high precision. If the multiple results are all over the place, and the average result is off target, then you have low accuracy and low precision. For example, it helps to imagine a dart board with a few darts. If all the darts are together after being thrown, that is precision. When the thrown dart is close to the bullseye, that is accuracy. IF the darts are all close together and all on the bullseye - that is accurate and precise...if they are all close together, but way off the bullseye, then that is precise but NOT accurate, and so on...
What determines the precision of a calculated result based on measurements?
The precision of a calculated result based on measurements is determined by the precision of the measurements themselves. The more precise the individual measurements are, the more precise the calculated result will be. Additionally, the number of significant figures in the measurements and the mathematical operations involved also affect the final precision of the result.
What is accuracy?
Precision -- the degree to which the result of a measurement, calculation, or specification conforms to the correct value or a standard
What does accuracy and precision mean?
Precision measurements are those which are repeatable - so all measurements are clustered around the same value. An accurate measurement is where you are close to the true value. A measurement can be precise but not accurate. If you have a piece of string which is 75cm long. You measure it and come up with values of 60cm, 60.5cm and 59.5cm - your measurements are precise but not accurate. See also 'The Story of Measurement' by Andrew Robinson.

How does accuracy differ from precision a scientific measurement?
Accuracy refers to how close a measured value is to the true value, while precision refers to how close multiple measurements are to each other. In scientific measurement, accuracy indicates the system's ability to measure the true value, and precision describes the system's consistency in producing similar results.
