When do we say measurement is precise?
A measurement is considered precise when it yields consistent and reproducible results under the same conditions, regardless of whether those results are close to the true value. This means that repeated measurements will show little variation from each other, indicating a high degree of reliability in the measurement process. Precision does not necessarily imply accuracy; a precise measurement can still be systematically off from the actual value.
what is the difference between accuracy and precision?
''Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.
How close a measurement is to the actual value?
This is termed the accuracy of the measurement.
What is meant by measurement is accurate but not precise?
An accurate but not precise measurement would be an approximate measurement. For example, in cooking or baking, the ingredients list might indicate one cup of a certain item. Scientifically, however, one cup, (or 8 ounces) would not be a precise measurement for testing purposes. Instead, a precisemeasurement would be required, especially when the results of a specific test need to be reproducible and the quantities are minute, as in micrograms, for example. Accuracy in measurement is of closeness to the actual or exact, but precision in measurement is closeness to the same spot each time it is taken.
What is a measurement close to the true or accepted value?
The term is accuracy
What is a fundamental measurement that is defined by a readily reproducible reference standard?
The meter is a fundamental measurement defined by a readily reproducible reference standard. It is based on the speed of light in a vacuum and is used to quantify length or distance.

What is a measurement close to true size?
A measurement close to true size is referred to as Precision Measurement.
what is the difference between accuracy and precision?
''Accuracy is the degree of closeness to true value. Precision is the degree to which an instrument or process will repeat the same value. In other words, accuracy is the degree of veracity while precision is the degree of reproducibility.
Which term describes how close a measurement is to the true value?
Accuracy describes how close a measurement is to the true value.
Standards of measurement are chosen because they... a. are reproducible in another laboratory. b. cannot be destroyed by any common physical or chemical means. c.are easily changed.?
a. are reproducible in another laboratory. Standard measurements provide a consistent basis for comparing and reproducing results in different locations or by different researchers.
Why is the Breslow system of measuring the thickness of malignant melanoma the preferred method?
It turns out that the Breslow measurement is more reproducible and thus more useful; therefore, for purposes here, depth of penetration by absolute measurement (Breslow) is used in local staging.
What is a Description of how close a measurement is to an accepted or true value?
The accuracy of a measurement refers to how close it is to the accepted or true value. This can be assessed by comparing the measurement to a known standard or by considering the degree of error or uncertainty associated with the measurement.
How close a measurement is to an accepted?
When measuring, there are two types of deviation, accuracy and precision. A measurement is close to the accepted value when it his highly accurate.
How close a measurement is to the actual value?
This is termed the accuracy of the measurement.
How close is a measurement is to an accepted value?
When measuring, there are two types of deviation, accuracy and precision. A measurement is close to the accepted value when it his highly accurate.
What minimum requirement is needed to obtain reproducible results with a single-beam spectrophotometer?
To obtain reproducible results with a single-beam spectrophotometer, the minimum requirement is consistent sample handling and preparation, including precise measurement of sample volumes and concentrations. Additionally, maintaining stable environmental conditions, such as temperature and light, is essential to minimize variations. Regular calibration of the instrument and using appropriate blank and standard solutions also contribute to achieving reliable and reproducible results.
