- Types of Experiments
- Lab
- Refers to a controlled environment, eliminating any other variables besides those they want to examine
- Advantages
- High validity control over EV means cause and effect can be established
- High reliability - standardised procedures makes the experiments replicable
- Limitations
- Low ecological validity - artificial environment may result in HE therefore high DC
- Risk of researcher bias
- Advantages
- Refers to a controlled environment, eliminating any other variables besides those they want to examine
- Field
- Research conducted in the natural environment
- Strengths
- Higher ecological validity - represents real life better, means behaviour is more likely to be natural
- Low chance of DC
- Limitations
- Low validity due lack of control over EV which will result in CV
- Low reliability - lack of control over variables makes replicating the experiment difficult
- Vulnerable to sample bias
- Ethical issues of gaining informed consent + use of data
- Strengths
- Research conducted in the natural environment
- Natural
- examine the effect that manipulated variables (IVs) have on measured variables (DVs), i.e. causal effects.
- Advantages
- High ecological validity - behaviour examined is reflective of real life
- Limitations
- Ethical issues of consent - debriefing is required
- Low internal validity - unable to control variables
- Advantages
- examine the effect that manipulated variables (IVs) have on measured variables (DVs), i.e. causal effects.
- Quasi
- contains a naturally occurring IV. the naturally occurring IV is a difference between people that already exists
- Lab
- Correlation and experiments
- A correlation looks at the relationship between two variables
- An experiment is too test the effect one variable (IV) has on another variable (DV)
