Research Methods And Techniques Flashcards
Lab experiment
An experiment which is carried out in controlled settings
IV is manipulated to see effect on DV
EV’s are controlled for - matched pairs design eg
Ppts are randomly allocated to conditions
Ppts experience something for the purpose of the study
Field experiment
Carried out in natural environment
Realistic - more ecological validity
EV’s can’t be controlled for
Quasi experiment
Where the IV occurs naturally or is already established but can’t be manipulated (gender)
Observation
Observing behaviour and then recording it
Structured observation
Where a researchers makes a structure on the observation to meet its aim
Unstructured observation
Researchers records everything that happens
Naturalistic observation
Carried out in the real world
Controlled observation
Controls al factors which might affect behaviour
Participant observation
Where the observers are part of, or are pretending to be part of the group they are observing
Non participant observation
Where the observer isn’t a member of the group being studied
Overt observation
When participants know they are being observed
Covert observation
Ppts don’t know they are being observed
Self-report
Where ppts provide data about themselves
Interview
Ppts are asked questions face to face and their responses are recorded
Structured interview
Where the same set of questions is asked to each ppt in the same order
Semi structured interview
Interviewer has a list of questions but ppts can ask for clarification of particular answers or responses
Unstructed interview
When the researcher asks random questions
Questionnaire
Sets of questions answered by ppts
Structured questionnaire
Contains closed questions
Semi structured questionnaire
Contains open and closed questions
Unstructured questionnaire
Contains open questions
Correlational studies
Researcher tests to see if two variables are related
Positive correlation
As one variable increases, the other one does too
Negative correlation
As one variable increases, the other one decreases
No correlation
No relationship between the variables
Correlation coefficient
The strength of a correlation
IV
aspect of experiment which is manipulated to see effect on behaviour
DV
The measure of behaviour in an experiment
Design
The procedure used to control the influence of participant variables in an experiment
Extraneous variables
An undesirable variable which might affect the relationship between the IV and the DV
Conditions
The situation under which an experiment is undertaken
Controls
Aspects of the research which are kept the same for each condition
Standardised procedure
A procedure which has controls to ensure each ppt experiences the same thing
