CH 2 Research Methods (Terms) Flashcards
Naturalistic Observation
Type of Observational Research
Watching behaviour in a real-world setting without trying to manipulate the situation.
Participation Observation
Type of Observational Research
The observer becomes apart of the group or social setting being studied
Case Study
An in-depth analysis of an individual, social unit, event, or some other phenomenon.
Survey
Uses questionnaires to gather information about people
- Self-report measure
- Examine traits, beliefs, opinions, and feelings
- Can be descriptive/ used to test hypotheses
e.g., Personality Traits, Beliefs about distracted driving, Depression.
Correlation Design
A research design that examines the extent to which two variables are associated.
- A statistical association between variables
- Scores are associated in a non-random fashion
- Only measures things.
Experiment
Researcher:
- Manipulates one or more variable
- Attempts to control extraneous factors
- Measures how the manipulated variable affects participant’s responses
Participants are randomly assigned to groups or orders of conditions.
Population
Refers to all the cases or observations of interest in a survey research
Sample
A subset of cases or observations from the population in a survey research
Representative Sample
Reflects the important characteristics of the population in a survey research
Random Selection
A procedure that ensures that every person in a population has an equal chance of being chosen to participate
Reliability
Consistency of a measurement tool
- Measures can be reliable but inaccurate
Types
- Test-retest
- Interrater Reliability
Validity
The extent to which a measure assesses what it purports to measure
Key concept
Variables are measured not manipulated
Positive correlation
As X increases, Y increases
As X decreases, Y decreases
Negative Correlation
As X increases, Y decreases
As X decreases, Y increases
No (Zero) Correlation
No association between variables
Pearson’s R
A statics that measures the direction and strength of the linear relationship between two variables
Scatterplot
A graph that portrays the intersection of data on two variables for a single individual
Illusory Correlation
The perception of statistical association between two variables when none exists
Independent Variable
The variable manipulated by the researcher
Dependent Variable
The response that is measured, to determine whether the independent variable has produced an effect
- The presumed effect in the cause and effect relationship
