Research Methods Flashcards
Independent Variable
A variable that stands alone and isn’t changed by other variables you are trying to measure (the DV is dependent on this- e.g gender/age)
Dependant Variable
A variable that depends on other factors, and is measured (e.g. artistic ability)
Extraneous Variable
Any variable not being investigated that has the potential to affect the outcome of a research study
Confounding variable
A third variable that influences both the independent and dependent variables
Control condition
A condition that is used as a standard of comparison in a scientific experiment
Lab Experiment
An experiment in a controlled environment, with a controlled IV
Experimental condition
A level of the independent variable that is manipulated by the researcher to assess the effect on a dependent variable
Natural Experiment
An experiment in a natural environment, with no set IV
Field Experiment
An experiment in a natural environment, with a controlled IV
Independent measures design
An experimental design in which you only assign participants to one of your experimental conditions
Repeated measures design
An experimental design where the same participants participate in each IV condition
Matched Participants Design
An experimental design where pairs of participants are matched in terms of key variables
Standardization
Keeping the procedure for each participant in a study (experiment/interview) exactly the same to ensure any differences between participants were treated
Reliability
The extent to which a procedure, task, or measure is consistent, for example, that it would produce the same results with the same people on each occasion
External Validity
Is it valid outside of the primary group (you are able to generalize it outside of the group to other situations and groups of people)
Internal Validity
Is it valid within the primary group (are they testing what they say they’re testing for?) - testing that it is not influenced by other factors or variables
Ecological Validity
Is it valid for the real world (is the ENVIRONMENT matching the real world?)
Generalisability
How widely do findings apply to other settings and populations
Mundane realism
Is the ACTION match the real world? (is it valid for the real world)
Self Report
A questionnaire/survey/interview that obtains information from the participants about themselves
Questionnaire
A set of questions that is sent out to collect data from a variety of people to reach a conclusion
Closed Question
A question sent out in a questionnaire with direct, set answers (“How many months has your leg been hurting?”)
Open Question
A question sent out in a questionnaire with an open, longer answer (“How was your day today?”)
