Explore different sampling methods to ensure your research reflects the big picture.

Types of Statistical Sampling

Probability sampling gives every member of a population a known chance of being selected.

Probability Sampling

Each population member has an equal chance of being chosen. Imagine picking names from a hat!

Everyone Gets a Shot

Select a starting point and choose every nth member after that. Like picking every 10th person in line.

Systematic Sampling

Divide the population into groups (strata) and choose proportionally from each.

Stratified Sampling

Group the population, then randomly select clusters to study

Cluster Sampling

When randomization isn't feasible, these methods rely on researcher judgment, like interviewing readily available participants.

Non-Probability Sampling
