Practical Issues in Psychological Research Flashcards
(33 cards)
What are the problems with sampling as a practical Issue?
- Some ppts may be found more easily than others.
- May be time consuming and expensive to gather appropriate sample.
- Sample may not be representative and bias free.
How are variables used in practical Issues?
- Deciding on how to measure variables are difficult.
- Must have an cause and effect relationship between variables through minimising EVs can be time consuming and costly.
- The data gathered must be available and be able to be gathered.
What are the problems with methadology as a practical Issue?
- Having the resources and money to carry out the procedures.
- Deciding on the right method for the topic being studied.
- Deciding on the control group/ Decide whether the appropriate data collection tools may be limited
How are materials used in practical Issues?
- may need a recording device if using an observation or paper if it is memory
How are data collection tools used in practical Issues?
- Practical Investigation involves preparing data collection tools so you can draw on your own experiences when considering issue
How do you data bias in practical Issues?
- consider demand characteristics of the study and aim to avoid them by not making the purpose of the study obvious.
How do you collect the data and prepare it for analysis in practical Issues?
- deciding whether an observation will be participant, non-participant, covert or overt. Preparing the data for analysis - how the data will take place and how you will display the data
What is generalisability?
- Is the application of the results from a study, to the wider target population
What is reliability?
- Is a measure of whether something stays the same, i.e. Consistent.
What is internal reliability?
- This describes the internal consistency of a measure.
What is external reliability?
- Refers to extent to which a measures varies from one use to another
what is test re-test reliability?
- A measure of whether something varies from one time to another
What is inter-rate reliability?
- Degree of agreement between raters/observers
What is validity?
- Refers to whether a study is measuring the behaviour it tends to measure.
What is Internal validity?
- How well the procedure establishes a cause and effect relationship
What is construct validity?
- how well the measure is being used is a useful indicator of what is supposed to be studied
What is predictive validity?
- The extent to which the performance on the measure can predict future performance on a similar criterion
What is Triangulation?
- Using multiple studies on the same topic and comparing results
What is external validity?
- how well the study applies to real life
what is population validity?
- the extent to which findings apply to other populations than those used as the sample.
what is ecological validity?
- Refers to the extent to which the research can be generalised to real life/everyday situations.
what is mundane realism?
- the extent to which the task reflects ordinary life.
what is objectivity?
- Is a feature of science and is something is objective it is not affected by the personal feelings and experiences of the researcher.
what is subjectivity?
- Refers to when the findings are affected by personal feelings, prejudice and interpretations.
