Simple random sampling
is the most basic form of probability sampling. It involves just one step, and each survey subject is selected independently from the other members of the population or sample frame. A standard method of random sampling is assigning every individual in the sample frame a unique number.

How do you select participants in a survey?
Random selection
refers to the method used to select your participants for the study. For example, you may use random selection to obtain 60 participants by randomly selecting names from a list of the population. Random assignment is used to form groups of participants who are similar.
What are the two types of sampling methods?
- Probability sampling involves random selection, allowing you to make strong statistical inferences about the whole group.
- Non-probability sampling involves non-random selection based on convenience or other criteria, allowing you to easily collect data.
