hope it help

In statistics, the concordance correlation coefficient measures the agreement between two variables, e.g., to evaluate reproducibility or for inter-rater reliability.

Answer 2

PRECISION

Precision is concordance between (B) true value and observed value

KEY POINTERS TO DEFINE PRECISION IN DETAIL:

* The degree of reproducibility or agreement between repeated measurements is referred to as precision.

*The lesser the inaccuracy will be the more measurements you take and the more precise they are.

* Precision, also known as reproducibility or repeatability, refers to the degree to which identical results may be obtained by repeating measurements under the same conditions.

* A measurement system's precision relates to how closely repeated measurements coincide (which are repeated under the same conditions). Measurements can be precise but not accurate, accurate but not precise, or neither.
