Sampling Methods in Psychology

These flashcards cover various sampling methods used in psychology research, including definitions and characteristics.

Random Sampling

An ideal approach to make a sample representative where every member of the target population has a chance of being included.

Stratified Sampling

A sampling method where the researcher decides on essential characteristics the sample must reflect and recruits participants to maintain these proportions.

Convenience Sampling

A method of recruiting participants that are easily available, usually used when resources and time are limited.

Self-Selected Sampling

A sampling technique where participants volunteer to be part of the study, which can lead to biased results due to self-selection.

Quota Sampling

A method where the researcher sets a quota for specific characteristics and recruits participants until this quota is met, regardless of how they are selected.

Purposive Sampling

A technique where participants are intentionally selected based on specific characteristics or criteria relevant to the research.

Theoretical Sampling

A specialized form of purposive sampling that continues until data saturation is reached, meaning no new information is obtained.

Snowball Sampling

A technique where existing study participants recruit future subjects from among their acquaintances, useful for hard-to-reach populations.
