CONTROLLING VARIBLES (HOW) Flashcards
1
Q
Name 3 ways that a research can control variables
A
- Standardisation
- Operationalisation
- Randomisation
- Random allocation
- Blinding
- Pilot testing
- Objective measures
- Counterbalancing
- Control groups
2
Q
How does standardisation control variables?
A
- Minimises situational varibles by ensuring all ppts had the same experience.
- Reduces measurement error by providing clear, consistent guidelines for adminsitering tests. Easier replication.
3
Q
How does operationalisation help control variables?
A
- Ensures variables are manipulated and measured consistently with no ambiguity or subjectivity.
4
Q
How does random allocation control variables?
A
- Individual differences are less likely to affect results as each ppt has an equal opportunity to be assigned to any given group so ppt variables are evenly spread out across conditions .
5
Q
How does randomisation control for varibles?
A
- Helps ensure potential confounding variables are evenly distibuted across experimental groups.
6
Q
How does blinding control for variables?
A
Reduces
* Demand characteristics
* Investigator effects
* Expectancy effects
7
Q
How does pilot testing control for varibles?
A
- Researchers can identify any problematic confounding variables, inconsistencies, or problems with the measures and make necessary adjustments to improve their reliability.
8
Q
How does counterbalancing control for variables?
A
*Controls for order effects
9
Q
How do control groups control for variables?
A
- Provides a baseline against which the iv can be compared.
- As controls are exposed to identical conditions to the EG, researchers can control any CV and isolate the effects of the IV
10
Q
How do objective measures control for variables?
A
- Contributes to the establishment of casual relationships
- Concise and consistent assesments of the phenomena
