A testible statement about the relationship between two variables
Hypothesis
1 of 20
The factor which will be varied/changed in an experiment to look for an effect on the other variable
Independent Variable
2 of 20
The factor which will be measured in an experiment to see if changing the Independent Variable had an effect
Dependent Variable
3 of 20
A hypothesis that exists and states that no variables can affect any other variables.
Null Hypothesis
4 of 20
Where two or more separate groups of participants are used in an experiment; each group takes part in one of the conditons.
Independent Groups
5 of 20
Where people with similar qualities are grouped into pairs; each member of the pair takes part in a different condition.
Matched Pairs
6 of 20
A research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods.
Repeated Measures
7 of 20
An in-depth investigation of an individual, a small group, or an organisation.
Case Study
8 of 20
A research method collected by observing and then recorded.
Observational Method
9 of 20
A variable that is not the Independent Variable but might affect the Dependent Variable if it is not controlled.
Extraneous Variable
10 of 20
Using chance to provide an order for a procedure.
Randomisation
11 of 20
The results of an investigation can be said to apply to real-life behavior; they are an accurate of behaviour in the real world.
Ecological Validity
12 of 20
People who are members of the target population and are available and willing to take part in research.
Opportunity Sample
13 of 20
Every member of the target population has an equal chance of being selected for the sample.
Random Sampling
14 of 20
A research method which involvs studying behaviour as it happens and recording date in the form of notes or videos.
Observation
15 of 20
Data in the form of spoken/written words or in another on-numerical form.
Qualitative Data
16 of 20
Data in the form of numbers.
Quantitative Data
