Precision is a description of random errors, a measure of statistical variability.
Accuracy has two definitions:
More commonly, it is a description of systematic errors, a measure of statistical bias; low accuracy causes a difference between a result and a "true" value. ISO calls this trueness.
Alternatively, ISO defines accuracy as describing a combination of both types of observational error above (random and systematic), so high accuracy requires both high precision and high trueness.In simplest terms, given a set of data points from repeated measurements of the same quantity, the set can be said to be precise if the values are close to each other, while the set can be said to be accurate if their average is close to the true value of the quantity being measured. In the first, more common definition above, the two concepts are independent of each other, so a particular set of data can be said to be either accurate, or precise, or both, or neither.
Too many 45’s in the safe, so I’m looking for a new home for this Glock 21 Gen4. Hard case and 3 mags included, just as it came from the factory.
I should keep it, as it’s surprisingly accurate but something’s gotta go.
FFL transfer required, buyer responsible for fees.
PM me if...
Accurate and compact, with a very smooth action and surprisingly lighter recoil compared to a similar-sized Glock 43.
