Question
Chapter 3, Problem 11STP
Interpretation Introduction
Interpretation : The statement I and II are true or false is to be decided and check whether statement II is the explanation for statement I.
Concept Introduction : Accuracy refers to how closely the value being measured matches the actual value in a measurement. Precision is a measurement of how well two measurements match one another, regardless of the actual value.
Expert Solution & Answer
Answer to Problem 11STP
Statements I and II are false.
Explanation of Solution
Correct and reproducibility are the two features of measurement.
The concepts of accuracy and precision are related to correctness and reproducibility respectively.
Accuracy refers to how closely the value being measured matches the actual value in a measurement. Precision is a measurement of how well two measurements match one another, regardless of the actual value.
Accuracy is evaluated by comparing the correct value with the measured value in a measurement.
Precision is evaluated by comparing the two or more repeated values in a measurement.
Precise measurement will not be accurate always. If the measurement has an error, it reflects in the precise value, So, the precise value is not accurate as always.
A value that is measured 10 times in a row gives precise results not an accurate result.
The accuracy is a different phenomenon.
