Paper 1 - Research Methods Flashcards
What are the 4 methods of research ?
self report
observation
experiment
correlation.
What is a self report ?
Any data collection that involves asking people to report their thoughts, feelings and behaviours.
What are the advantages and disadvantages of a self report ?
- they give first hand accounts.
- they may not be accurate as people may not know why they do or feel things. also people may give demand characteristics or put a good impression across.
What is a questionnaire ?
Respondents record their own answers to a set of fixed questions (predetermined) in written form.
What are the advantages and disadvantages of questionnaires
- can be easily repeated so that days can be collected from large numbers of people, relatively cheap and quickly. Respondents may feel more willing to reveal personal/confidential information in a questionnaire compared to an interview.
- the sample may be biased as only a certain type of person will fill in a questionnaire- liberate people who are willing to spend their free time filling it in.
what is a closed question ?
a question that has a fixed number of possible answers.
What are the advantages and disadvantages of closed questions ?
- easy to analyse because it gives quantitative data which can be used to find averages and graphs which are generally easy to make conclusions from.
- may not allow people to express their precise feelings so data may be low in validity.
- oversimplifies reality and human experience because it suggests simple answers.
what’s an open question ?
a question where respondents are invited to provide their own answer
what are the advantages and disadvantages of open questions.
- provided good detail on how people behave because they’re given the opportunity to express themselves without being limited to predetermined categories which can increase data validity.
- more difficult to detect trends and draw conclusions because of the wide range of answers (qualitative data). Researchers may tend to look for trends rather than descriptive statistics.
what are the advantages and disadvantages of rating scales ?
- reasonably objective way to represent feelings and attitudes towards a topic
-provided quantitative data which is easy to draw graphs from and analyse. - respondents may go for the neutral option which may not reflect true feelings and may lower validity of the data.
how may clarity affect data of a questionnaire ?
if the respondent doesn’t understand the question they may give a meaningless answer which will decrease the validity of the data. this can be caused by double negatives, slang, ambiguous questions and double barrelled questions.
what types of bias may affect a questionnaires validity.
- leading questions: questions that cause the respondent to lead towards an answer that’s desired by the researcher.
- social desirability bias: giving a ‘good impression’ to the researcher.
- This provides meaningless answers which decreases the validity of the data.
what’s a likert rating scale ?
allows respondents to state how much they agree or disagree with something.
what’s a semantic differential rating scale ?
measuring people’s attitudes towards something.
what are interviews ?
questions are verbally delivered in real time, respondents answer each question as it is presented by the interviewer.
what are advantages and disadvantages of interviews ?
- the respondent can ask the interviewer questions eg explanation on a question. questions can be adapted during the interview.
- people may reveal more information as a skilled interviewer can encourage a thorough response.
- numbers are limited due to how much time they take and finding a skilled interviewer which are more expensive.
what’s a structured interview ?
predetermined questions are delivered by an interviewer who doesn’t prove beyond the answers given but can answer any questions given by the respondent.
what are the advantages and disadvantages of structured interviews ?
- can be easily repeated. easy to analyse as answers are more predictive.
- the interviewers expectations may influence the answers given by the respondent - interviewer bias.
what are semi structured interviews ?
some questions are predetermined but some questions can be developed as the interview proceeds.
what are unstructured interviewers ?
no questions are predetermined.
what are the advantages and disadvantages of semi and unstructured interviews ?
- more detailed information can be obtained because questions are more specific to the participant
- can access more information than a structured interview.
- more affected by interviewer bias than structured interviews because new questions may be leading questions.
- requires well trained interviewers which are more expensive.
what’s primary data ?
first hand days a researcher collected using a observation, self report or experiment.
what’s secondary data ?
second hand days. researchers may make use of data that’s already collected eg by the government
what’s inter rater reliability ?
the consistency between two different interviewers
why may inter rater reliability be low ?
if interviewers behave differently
how can inter rater reliability be evaluated ?
two or more interviews will question the same person and the data will be compared. if the scores are the same it’s reliable
what’s external reliability ?
the consistently of something overtime - wether something varies from one time to another.
how would you evaluate external reliability ?
test re test: give the same person the same psychological test on 2 occasions to see if the same results are obtained. the time between tests must be long enough that the participant cannot remember their previous answer but not too long that their behaviours and feelings have changed.
what’s internal reliability
a measure of wether a questionnaire(study) is consistent in itself.
how would you evaluate the internal reliability ?
split half method : the tests items are split into two halves and scores on both halves are compared. if the scores are similar it’s reliable.
what’s external validity ?
the extent to which the data from the study can be generalised beyond the study.
what are the types of validity within external validity and their meanings
- population validity: the extent to which the data collected from a study can be generalised to other groups of people beyond the sample used.
- ecological validity: the ability to generalise a research effect beyond the particular setting it occurred in compared to other real life settings.
what’s internal validity
concerns wether the test itself assessed what it’s intended to assess
what are the types of validity within internal validity and their meaning ?
- face validity : wether the items on a test look like they asses what they intent to assess.
- construct validity: wether the tests assessed the underlying concepts/ theories on that topic and the extent to which they’re represented on the questionnaire.
- concurrent validity: concerns comparing the performance on a new test compared to a validated previous test on the same topic. if the data collected is similar the questionnaire had concurrent validity
- criterion validity; concerns wether the data collected can predict a future behaviour/ attitude.
in a self report what may the reliability of someone’s answer be affected by
- ambiguous questions - they may respond differently every time
- change in attitudes toward something.
what are observations
watching or listening behaviour, recording it and looking for patterns. the observations can be put into categories
what are the advantages and disadvantages of observations ?
- sometimes what people say they do is different to what they actually do so observations give a different outlook on behaviour compared to self reports.
- covert observations allow for the collection of data without the participants knowing. this increases validity of the results as there are less demand characteristics.
- observations cannot provide information for what people think or feel.
why do observations need systematic procedures ?
to make sure they’re objective.
what are behavioural categories in observations ?
objective methods to separate continuous streams of actions into components the categories are arranged as a list easy with a code frame.
