See below.

Explanation:

A precise measurement means that in a repetition of an experiment the results are all very close. Note precise is not always the same as accurate. If there is say 32.0% of lead in a sample of lead ore and 2 analyses give results of 31.92% and 31.93% they are very precise, but if another 2 analyses give results of 31.95% and 32,05% they are less precise but more accurate.
