RESEARCH METHODS
EXPERIMENTAL METHODS
- null hypothesis- states something is due to chance and not IV
- Hypothesis
- Directional (one-tailed)
- It predicts the directions in which change is expected to occur
- E.G- bigger/ smaller, increase/decrase
- It predicts the directions in which change is expected to occur
- Non-Directional ( two-tailed)
- Simply predicts change and does not specify direction
- E.G- effect, change, difference.
- Simply predicts change and does not specify direction
- Directional (one-tailed)
TYPES OF EXPERIMENTS
- LABORATORY EXPERIMENT
- highest level of control - controlled environment
- DISADVANTAGES
- loss of ecological validity
- drawbacks of experimental design
- demand charachteristics
- sampling bias
- ethics
- loss of ecological validity
- DISADVANTAGES
- controls situational variables
- ADVANTAGES
- Complete control over variables
- quantitative data
- able to use technical equiptment
- quantitative data
- forces pace of research
- easy to replicate
- internal validity
- Complete control over variables
- ADVANTAGES
- highest level of control - controlled environment
- FIELD EXPERIMENT
- carried out in an everyday environment
- experimenter still manipulates the IV
- carried out in an everyday environment
- NATURAL EXPERIMENT
