Reliability
Refers to how consistently a test measures something (repeatable).
What is reliability?
Refers to how accurately a test measures what it is intended to measure.
What is validity?
The term for what is being manipulated/altered or changed in an experiment.
What is an independent variable?
An experiment where the researcher has strict control over variables and uses standardised procedures in a controlled environment.
What is a laboratory experiment?
Refers to the consistency within a test.
What is internal reliability?
Refers to whether the test appears (at face value) to measure what it claims to.
What is face validity?
The term for what is being measured in a study.
What is a dependent variable?
The experiment takes place in the subject's own natural environment.
What is a field experiment?
This can be assessed by measuring the extent to which different observers achieve similar results when observing and scoring the same participants
What is inter-rater reliability?
Does the experiment ‘mirror’ the real world and resembles events in normal everyday life?
What is mundane realism?
Something that might interfere with the Dependant Variable (DV). Sometimes referred to as uncontrolled variables.
What is an extraneous variable?
Cues that may indicate the research objectives to the participant, thus influencing results.
What is a demand characteristic?
Where a person is given a questionnaire/interview/test on one occasion, and then this is repeated again after a reasonable interval.
What is test-retest reliability?
The extent to which we can generalise to different periods in time, e.g. is a study from the 1950s really applicable to behaviour displayed today?
What is Historical/temporal validity?
Numbers-based, countable or measurable data, is about quantities.
What is quantitative data?
Something that has definitely interfered with the DV (dependent variable) and confounded the result.
What is a confounding variable?
A statement or prediction of what results you expect to find after your experiment.
What is a hypothesis?
refers to the ability to produce the same findings every time the test is carried out.
What is external reliability?
The extent to which the results of a study can be generalized to other settings (ecological validity), other people (population validity) and over time (historical/temporal validity) outside of the study.
What is external validity?
Descriptive information and regards phenomena which can be observed but not measured, such as language.
What is qualitative data?
An extraneous variable that is an outside influence on an experiment eg time of day, weather, or noise
What is a situational variable?
A statement or prediction that there will be no difference between the variables.
What is a null hypothesis?
