Replicates and Resolution

Replicate Mean Is Pinned

readings before report

A reported mean is forced by the replicate readings. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Replicates are separate physical readings

The readings are 12, 14, and 16.

The mean is pinned by the readings

Their sum is 42, so the mean is 14.
