Involves the manipulation of an independent variable to measure the effect on the dependent variable. Experiments may be laboratory, field, natural or quasi.
1 of 9
Aim
A general statement of what the researcher intends to investigate; the purpose of the study
2 of 9
Hypothesis
A clear, precise, testable statement that states the relationship between the variables to be investigated. Must include independent variable (IV), dependent variable (DV) and self report technique
3 of 9
Directional hypothesis
States the direction of the difference or relationship
4 of 9
Non-directional hypothesis
Does not state the direction
5 of 9
Variables
Any 'thing' that can vary or change within an investigation. Variables are generally used in experiments to determine if changes in one thing result in changes to another
6 of 9
Independent variable (IV)
Some aspect of the experimental situation that is manipulated by the researcher -or changes naturally - so the effect on the DV can be measured
7 of 9
Dependent variable (DV)
The variable that is measured by the researcher. Any effect on the DV should be caused by the change in the IV
8 of 9
Operationalisation
Clearly defining variables in terms of how they can be measured
