Discussion:
Sampling is using a subset of a set of data to determine the overall characteristics of the set. From Wikipedia, the three main advantages of sampling are that the cost is lower, data collection is faster, and since the data set is smaller it is possible to ensure homogeneity and to improve the accuracy and quality of the data.
