Accuracy and precision can be confusing but it doesnt have to beSubscribe. Httpbitly2wJ0DHa Score high with test prep from Magoosh - Its effective. For Example- The appropriate value of pi is 314 and its accurate approximation.
As an estimator of a normal population mean mu the sample mean hat mu bar X is unbiased.
Lets take a slightly more formal look at those two terms as a start. Precision is usually expressed in terms of the deviation of a set of results from the arithmetic mean of the set mean and standard deviation to be discussed later in this section.
