Research Methodologies (Page 1)

Vocabulary flashcards covering key concepts from Page 1 notes on research methods.

Experimental methodology

A systematic approach using controlled conditions to test the relationship between independent and dependent variables. Explains behavior

Hypothesis

A proposed statement that predicts a causal relationship between variables to be tested.

Independent variable

The variable deliberately manipulated to observe its effect on the dependent variable.

Dependent variable

The variable measured to assess the effect of manipulating the independent variable.

Controlled conditions

Conditions kept constant to isolate the effect of the independent variable.

Non-experimental methodologies

Research designs that do not involve manipulating variables, used when experiments are not possible or ethical. Describes behavior

Case studies

group of people or person examined through a event to provide info on a specific topic.

Correlational studies

Researchers test 2 variables to see how strong the relationship is.

Meta-analysis

Takes múltiple studies results to provide a claim on one topic.

Naturalistic observation

Watching people in the natural world to collect data so there is little to no interfernce

Hawthorne effect

participants change behavior because they know theyre being studied.

Third-variable problem (confounding variable)

a third variable that is uncontrollable happens when correlation studies don’t go as planned.

Causation

cause and effect. Correlation doesn’t cause causation.
