- formulating research questions- aims & hypothesis
- aims
- general idea for research (goal)
- always starts with 'to investigate'
- aim will always be given...
- first sentence of stimulus material or paragraph
- hypothesis
- a testable statement e.g research can be carried out on
- must be operationalised (made testable)
- clear, precise and measurable
- must have the word 'significant' in it
- must have all variables being studied in it
- you can only ever accept or reject a hypothesis - NEVER prove it
- difference between Aim & hypothesis
- aim
- clear statement about WHY research is taking place
- example: to investigate if boys are more aggressive than girls
- hypothesis
- precise testable statement containing predictions
- example: boys will be significantly more aggressive after watching boxing matches on tv for 2hrs than girls who watched boxing matches on tv for 2hrs
- aim
- types of hypothesis
- directional (one tailed)
- predicts actual direction of results
- e.g which group will score higher
- carried out when there's previous research that is consistant
- predicts actual direction of results
- non directional (two tailed)
- predicts that there is a difference or relationship between two sets of results but it does NOT state direction
- used when either outcome could occur and there is no pervious research or there is conflicting research
- directional (one tailed)
- aims
