Research Methods Flashcards
Reliability
If you repeat the experiment you get the same results
Validity
The true picture of what is being studied
Ethics
The morality of the study
Example of ethics
Privacy of participant should not be invaded, sensitivities, physical social and mental well being should not be harmed, and consent.
Advantages of closed questionnaires
Quick to complete, quantitative data, easy to repeat, allow comparisons to be made
Disadvantages of closed questionnaires
The answers can’t be properly explained, no follow up questions can be asked to get more in depth data, participant may not agree with any answers in a question
What are closed questionnaires?
Very structured with the participant having a few set answers to choose from
What are open questionnaires?
Less structured, a set of questions with no set answers to choose from, usually interview rather than written questions
Advantages of open questionnaires
Participant can truly express their meaning with no set answers, provide richer data such as follow up questions and qualitative data
Disadvantages of open questionnaires
Qualitative data is hard to quantify and analyse and therefore harder to compare, possible misinterpretations
What are postal questionnaires?
Participant fills out themselves and returns by post or internet
Advantages of postal questionnaire
cheap, quick results, participants can respond whenever they want without an interviewer, and more likely to give personal/embarrassing responses in privacy, less risk of interviewer bias
interviewer bias
where the interviewer makes assumptions based on the participant and therefore misinterprets
disadvantages of postal questionnaires
low response rate due to no pressure to complete, more unemployed or elderly responses, did the correct person answer? and no chance of follow up questions and chance of misunderstanding
longitudinal survey
follow the development of the same subject over a long period of time
