Accuracy refers to the degree of conformity of a measured or computed value to the true or correct value. In simple terms, it's the level of closeness between the measured or computed value and the true or correct value.
For example, if you're measuring the length of a table with a ruler and the true length of the table is 100 cm, but you measure it as 98 cm, your measurement is considered to be accurate because it is very close to the true value. However, if you measure it as 120 cm, the measurement would be considered inaccurate because it is quite far from the true value.
Accuracy can also be defined as a measure of the degree of freedom from error of a system, device or process. It can be determined by the amount of error or uncertainty of a measurement, or by comparing the measurement with a known or accepted standard. Accuracy is also used in other areas such as :
- In mathematical modelling, accuracy represents the degree of agreement of a computed solution with the true solution.
- In machine learning and data analysis, accuracy represents the degree of agreement of a model's predictions with the true values.
- In scientific experiments, accuracy represents the degree of agreement of a measured value with the true or accepted value
It's important to note that accuracy doesn't necessarily indicate the level of precision. A measurement can be precise, meaning that repeated measurements give similar results, but not accurate, meaning that the measurements deviate substantially from the true value.
