Question

What is the difference between curacy and precision

Answer 1

Answer:

B) Accuracy is how close a measured value is to its true value, while precision is how close measured values are to each other

Explanation:

i. The true value is the actual or correct value of the quantity measured. So that accuracy describes how close a measured value is to the true value.

For example, a pencil of actual length 10 cm is given to 3 students to measure individually.

Assume that each student measures; 9.5 cm, 9.65 cm, 9.95 cm. Then it can be observed that the 9.95 cm measure is accurate compared with the actual value.

ii. Precision describes the closeness of measured values to each other.

For example, a pencil of actual length 10 cm is given to 3 students to measure individually.

Assume that each student measures; 9.5 cm, 9.55 cm, 9.60 cm. Then their measurements are precise, though not accurate.
