• You must carefully consider how you will choose a sample that is representative of the group as a whole if you want to make accurate conclusions from your data. It is referred to as a sampling method. There are two main types of sampling techniques you might employ in your research: probability sampling, which uses random selection to let you draw conclusive statistical conclusions about the entire group, and convenience sampling.
