Accuracy refers to how close the measured value is to the true value, while precision refers to how close the measured values are to each other. A measurement that is both accurate and precise will be close to the true value and have very little variation among repeated measurements. Accuracy can be evaluated by comparing the measured value to a known standard, while precision can be assessed by determining the consistency of repeated measurements.

What is precision and accurancy?
Precision is how to keep track of good a measuring device is. Accuracy is how close an answer is to being correct. Something can be precise but not accurate. Something can be accurate but not precise.
What does precision mean in scientific term?
Accuracy is how close you are to your expected value and precision is how close together your experimental values are.
What does precision in science terms mean?
If you are trying to ask "what does precision in science mean" then I can begin to answer your question. Precision in measurement is a way of deciding how accurate a measurement is. If I were to measure my height with a ruler stick and a pencil against a wall I would expect the measurement to be accurate to a few millimetres. This is usually expressed in scientific terms as "plus or minus" so many millimetres. It is considered unscientific and unfair to describe measurements you may make in scientific work to a greater precision than you can actually make. I am about 5.9 metres (+- 1 cm) but it would be inaccurate and unscientific to say that I was 5.9354 metres tall. JCF
What is the difference between vernier caliper and micrometer size in terms of material measured?
A typical micrometer screw gauge has a maximum accuracy of ±0.005 mm (0.01 mm readings) whereas a vernier caliper has a typical maximum accuracy of ±0.05 mm (0.1 mm readings). Of course, different versions might have better or worse accuracy. They are also used differently because of their different shapes and forms.
Why aren't lighter and heavier sufficient descriptors?
Lighter and heavier are relative terms that lack specificity and precision in measurements. They do not provide enough information about the actual weight of an object in comparison to a standard unit of measurement. In scientific or technical contexts, using precise measurements or numerical values is preferred for accurate communication.

What terms refers to the exactness of a measurement?
The term that refers to the exactness of a measurement is "accuracy." Accuracy indicates how close a measured value is to the true or accepted value. Additionally, "precision" is often used to describe the consistency of repeated measurements, but it does not necessarily imply closeness to the true value.
How are the terms deviation and error related to accuracy and precision?
Deviation refers to the difference between a measured value and a reference or true value, while error is often used interchangeably with deviation but can also encompass broader notions of inaccuracies in measurements. Accuracy indicates how close a measured value is to the true value, while precision reflects the consistency or repeatability of measurements. High precision with significant deviation from the true value indicates that measurements are consistent but not accurate, whereas high accuracy with low precision indicates that measurements are close to the true value but vary widely. Thus, understanding deviation and error is essential for evaluating both accuracy and precision in measurements.
What does precision mean in scientific term?
Accuracy is how close you are to your expected value and precision is how close together your experimental values are.
What is concerned with the reproducibility of measurements?
The term repeatability is usd for an experiment realized by a single person.Reproductibility is used for an experiment realized by two or more persons.
What is the difference between 6mm and 1/4 inch in terms of measurement accuracy and precision?
The difference between 6mm and 1/4 inch is very small in terms of measurement accuracy and precision. 6mm is slightly larger than 1/4 inch, but the difference is minimal and may not be noticeable in most practical applications. Both measurements are precise and accurate for most everyday purposes.
How are precise and accurate measurements evaluated?
precision and accuracy are defined terms in science.Accuracy is the closeness of a given result to the true value of a measurement. Precision of a result is represented by the scatter of a number of measurements.True value is the average of a number of careful measurements by different experimenters, using different measuring systems. (consider the height of a mountain for example.)Resolution is merely the number of digits in the answer, and of which several may be meaningless.
What are the differences between a caliper and a vernier, and how do they compare in terms of accuracy and precision in measuring objects?
A caliper is a measuring tool with two jaws for measuring the distance between two points, while a vernier caliper has an additional scale for more precise measurements. Vernier calipers are generally more accurate and precise than regular calipers due to the additional scale, allowing for measurements to be taken to a higher degree of precision.
How do you calculate precision?
Accuracy describes the correlation between the measured value and the accepted value. The accuracy of a measurement, or set of measurements, can be expressed in terms of error: The larger the error is, the less accurate is the measurement. Precisiondescribes the reproducibility of a measurement. To evaluate the precision of a set of measurements, start by finding the deviation of each individual measurement in the set from the average of all the measurements in the set: Note that deviation is always positive because the vertical lines in the formula represent absolute value. The average of all the deviations in the set is called the average deviation. The larger the average deviation is, the less precise is the data set.
What are the terms of measurement?
The terms of measurement refer to the standards and units used to quantify physical quantities. Common terms include length (meters, centimeters), mass (kilograms, grams), time (seconds, minutes), and temperature (Celsius, Fahrenheit). Measurement also involves concepts like accuracy, precision, and calibration, which ensure that measurements are reliable and consistent. Understanding these terms is essential for scientific experiments, engineering, and everyday applications.

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.
