Question

Precision can be defined as the
exact center of a data set.
reproducibility of a measured value.
correlation between two variables that are measured in a data set.
agreement between a measured value and an accepted value.

Answer 1

Precision = reproducibility of a measured value.

Explanation: precision describes how close repeated measurements are to each other (low scatter). By contrast, accuracy is agreement with an accepted/true value; "exact center" refers to a measure of central tendency; correlation describes a relationship between variables.
