Sampling Methods
Probability Sampling
Simple Random
Every member has equal chance of selection
Stratified
Population divided into subgroups, then random selection
Cluster
Groups selected randomly, all members included
Systematic
Every nth member selected from a list
Non-Probability Sampling
Convenience
Easily accessible participants selected
Purposive
Specific characteristics targeted
Snowball
Participants recruit other participants
Quota
Specific proportions of subgroups included
Remember: Your sampling method directly affects the validity and generalizability of your results. Choose based on your research objectives, available resources, and target population characteristics.
