Research Designs Flashcards
Confounds
Factors that undermine the ability to draw casual inferences from an experiment
Correlation
Measures the associatin between two variables, if how they go together
Dependent variable
Variable that researchers measure but does not manipulate in an experiment
Experimenter expectations
When the experimenter’s expectations influence the outcome of a study
Independent variable
Variable that researchers manipulate and control in an experienced
Longitudinal study
A study that follows the same group of individuals over time
Operational definitions
How researchers specifically measure a concept
Participant demand
When participants behave in a way that they think the experimenter wants them to behave
Placebo effect
When receiving special treatment ot something new affects human behaviour
Quansi-experimental design
An experiement that does not require random assignment to conditions
Random assignment
Assigning participants to recieve different conditions of an experiment by chance
Research designs
Qualitative, correlational experiments, quasi-experimental
Qualitative design
Participant observation
Case study
Narrative analysis
Participant observation
Trying to study groups of people other than your own
Spend time with them and learn about them
Not used as much now
Case study
Therapeutic setting or group dynamics
Describe topic in much better detail
Issue is they focus on one and doesnt prove anything
Narrative analysis
Used by people studying racism
How people’s behaviour changes in environment they grew up in
How people behave and how they talk
Correlational design
Measured 2 variables and your accessing if someone’s score on one variable will impace other
- correlation coefficient
Experiment
Figure out what is causing changes in a and b
Sampling
Get few peoole to do test and then apply study to population
- 21% people in uni im population, get 21% uni grad to study
Need 1000 people to get accurate sample
Variable
Quality it characteristics of a person or situation thst can vary from person to person or situation to situation
- hair colour, height, age
Not variable
- people who have black hair
Independent variable
What you are manipulating
Dependent variable
Effect that happened later
Measuring variables
Self report
Other report
Overt report
Physiological measures
Self report
Simplest way to find variable
Ask people
Other report
Ask different person about person’s behaviour
Overt report
Watch people and monitor their behaviour
