measurements:
Week 1 weight: 4.8 lb
Week 2 weight: 5.3 lb
Week 3 weight: 4.9 lb
Week 4 weight: 5.4 lb
is the measurement accurate or precise?

Precision is the ability to reproduce a certain result in a repeated fashion.

The reading is not precise because, the same weight is not reproduced. Different values of weight was reported from each of the measurement process.
