Quantitative Research

Theory-based research focused on generating general laws of behavior via large samples and controlled conditions.

Lab Experiments

Research conducted in controlled conditions using a standardized procedure to ensure replicability and reliability.

Field Experiments

Research conducted in a natural setting where the researcher controls the environment to some extent.

Quasi Experiments

Research method that does not manipulate the independent variable and uses naturally occurring phenomena.

Natural Experiments

Research involving naturally occurring phenomena where the researcher cannot manipulate the independent variable.

Correlational Research

Analysis of the relationship between two co-variables without implying causation.

Surveys

Self-report method using questionnaires to gather large amounts of data, typically using closed questions.

Independent Measures Design

Research design where two groups of participants each experience one condition of the independent variable.

Random Sampling

Sampling method where every member of the target population has an equal chance of selection.

Convenience Sampling

Selecting participants who are readily available at a given time.

Volunteer Sampling

Participants self-select to join the research study often in response to advertisements.

Purposive Sampling

Participants are chosen based on specific characteristics relevant to the study.

Snowball Sampling

Participants are recruited through referrals from existing study subjects, often used for hard-to-reach populations.
