Question

module 1 exam cp chemistry a o / module 1: chemistry basics 11. explain the difference between accuracy and precision.

Explanation:

Accuracy refers to how close a measurement is to the true or accepted value. Precision is about how close multiple measurements are to each other. A set of measurements can be precise but not accurate (e.g., consistently off - target), accurate but not precise (e.g., scattered around the true value), both accurate and precise (e.g., clustered around the true value), or neither.

Answer:

Accuracy is closeness to true value. Precision is closeness of multiple measurements to each other.
