Planning and Conducting Research
Variables, operationalisation and control of extraneous variables
- 3 things to know
- Component 01
Overview
Recall questions on independent and dependent variables, operationalisation, control conditions, extraneous and confounding variables, investigator effects, standardised instructions and procedures, single-blind and double-blind procedures, and spotting uncontrolled variables in example studies.
What you need to know
Answer each one before you reveal it.
What is a control condition and why is one used?
What is the independent variable?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What is the independent variable?
Model answer
The variable that the researcher manipulates, or that varies naturally, in order to see its effect on the dependent variable.
- 2
What is the dependent variable?
Model answer
The variable that is measured in order to see whether the independent variable has had an effect.
- 3
What does it mean to operationalise a variable?
Model answer
To define it in precise terms that state exactly how it will be manipulated or measured.
- 4
Suggest an operationalised measure of aggression for an observation of children at play.
Model answer
The number of physical acts such as hitting, kicking or pushing recorded during a ten-minute period.
- 5
Suggest an operationalised measure of memory for a laboratory study.
Model answer
The number of words correctly recalled from a list of twenty after a delay of two minutes.
- 6
Why must variables be operationalised?
Model answer
So that the study can be replicated and other researchers know precisely what was manipulated and what was measured.
