- Aims and Hypothesis
- Research Aims
- Observe in order to construct a detailed picture of the interest.
- Use correlation to assess whether relationships between variables are predictable.
- Conduct experiments in order to understand and control cause and effect.
- All researchers aim to carry out ethically acceptable research that is valuable to research participants.
- Qualitative researchers may have different aims to the stages of building scientific knowledge.
- Hypotheses
- Null Hypothesis - there is no effect to be found.
- In experiment - 'The difference between the mean number of words recalled from STM after maintenance rehearsal and elaborative rehearsal was zero'.
- Correlation Studies - 'The correlation between 'aggresivity' in 7 year olds and the amount of time previously spent in day care is zero'.
- Alternative Hypothesis - there is an effect
- Directional Hypothesis specifies difference in an experiment. 'Mean A is higher than Mean B'.
- Non Directional Hypothesis is non committal about direction of difference or relationship. 'There is a difference between Mean A and Mean B'
