## Natural Resource Biometrics## Accuracy and Precision-
Two concepts that are often confused are
*accuracy*and*precision.*The following graphs illustrate the difference between these ideas. -
**Accuracy**of a sample is how close the sample mean (xbar) is to the population mean (mu). -
**Precision**of a sample is much confidence one may have in the estimated sample mean.
