- Research methods (2)
- correlational research
- looks for relationship between two variables
- strengths
- causal relationship- these can be ruled out if no correlation exists
- Ethics- study things that would be unethical to manipulate
- weaknesses
- causal relationships- cant be assumed as could be third unknown variable
- naturalistic observation
- weaknesses
- observer bias- can be subjective to the criteria and expectations can affect what they focus on
- Extraneous variables- affects behaviour
- strengths
- ecological validity- natural setting
- Theory development- on future ways to test behaviour in controlled setting
- weaknesses
- questionnaires
- can be face to face, on the phone or via internet
- strength
- collect large amount of information quickly (practical)
- weakness
- bad questions- leading questions or unclear affect validity
- biased samples- can be unrepresentative if one type of people respond
- ethics- confidentiality can be a problem esp around sensitive topics
- self-report people wish to present themselves in a good light (social desirability)
- interviews
- more conversational than a face to face questionnaire
- rich data- you can get detailed info as fewer constraints- unstructured
- pilot study- interviews are useful to get info before a study
- self-report - the results can be unreliable and affected by social desirability bias
- impractical - conducting interviews can be time- consuming and requires skilled researchers
- data analysis- analysing the data can be hard, particularly for qualitative data
- case studies
- rich data- study rare phenomena in a lot of detail
- unique cases- can challenge existing ideas and theories, and suggest future research ideas
- causal relationship- cause and effect of a relationship cannot be established
- ethics- informed consent can be hard
- content analysis
- involves assessing behaviour, words or concepts
- used to analyse secondary data
- inexpensive- usually easy and inexpensive to use
- ethics- there may be fewer ethical issue as pps aren't directly involved
- data analysis - can be time consuming
- subjectivity- interpretation and categorising can be subjective
- involves assessing behaviour, words or concepts
- correlational research
