what is the defination of accuracy & presicion?..

Accuracy means how close your result to standard value &
precesion means how near your individual value i.e.

One sample Which is 99 % assay gives to two analyst A & B

result of analyst A
98.6,99.7,98.7 Mean 99.0 Accurate

result of analyst B
99.0,99.1,99.0 Mean 99.0 Precise

what is the defination of accuracy & presicion?..

Accuracy: Accuracy is show u degree of reproducibility by

Precision: Precision is show u how precisice is ur method
by producing same result.

But remember one thing if u r method is precise is not
necessary it is accurate.

But if u r method is accurate it precise also.

what is the defination of accuracy & presicion?..

Accuracy : How close the measured value and the true vale.
Precision : How close the indipendent result obtaine from a
series of measurement
eg: value 9.7(a), 9.5(b),8.5(c) (if true value is 10, 9.7
is accurate)
8.5, 8.52, 8.51,8.53 ( precise but not accurate)
