Sampling Techniques
Advantage: When done correctly, a small percentage of the population can be selected which saves both time and money without sacrificing accuracy.
Disadvantage: Population characteristics may be over- or under-represented, leading to a generalization of results beyond the characteristics of the sample. This puts the validity at risk.

Advantages:
Easy to administer
Less costly and time consuming
Disadvantages:
The generalizability of the findings are limited to the characteristics of the subjects in the sample.
The sample may be biased.
