20. RM Questionnaires & Interviews Flashcards
Describe questionnaires.
-Gather personal data: attitudes, opinions, lifestyles. Any aspect of a persons life.
-Gather a large amount of information from a large sample in a relatively short amount of time.
-Can be administered by post, email, face to face or online.
-Should be completed anonymously.
-More straight forward questions come first followed by more in depth questions.
-Set of written questions, designed to collect information.
-Can discover what people think or feel (no guessing work like observations).
-Always pre-determined (structured).
-Can provide either qualitative or quantitative data.
What is a strength of questionnaires?
-Can be easily repeated so data can be collected from large numbers of people quickly.
-Respondents may feel more willing to reveal personal/confidential information than in an interview as they feel more anonymous.
What is a weakness of questionnaires?
-The sample of people involved may be biased because only certain types of people fill in questionnaires (literate individuals who are willing to spend the time filling them in).
-People don’t always tell the truth. Maybe because they don’t know what they think about a particular topic or how they’d behave in a particular situation. Or lack of truthfulness as they don’t want to look foolish or unlikeable so they present themselves in a way that makes them look better (this is social desirability bias).
Evaluate questionnaires as a research method.
-Questionnaires can be evaluated by considering reliability.
-If the questionnaire was carried out again, would the same results be found?
-Closed questions have forced answer choices, so are reasonably reliable.
-Questionnaires are set out and repeated exactly (standardised), this is a condition for reliability.
-Open questions allow for opinions to be given, so are less reliable.
How are questionnaires reliable?
Structured questions; the same for all respondents; so replicable and likely to be reliable.
How are questionnaires valid?
Set questions with forced-choice answers are likely to be less valid as may not yield ‘true’ data.
How are questionnaires open to subjectivity?
Structured format; less open to researcher bias in the analysis; closed questions do not require interpretation; open questions are likely to give short answers, so themes are clearer.
What are the 2 types of data?
-Quantitative
-Qualitative
Define quantitative.
Information that is or can be converted to numbers.
What is a strength of quantitative data?
Easier to analyse and can be summarised using descriptive statistics. This usually makes it easier to analyse as you can see at a glance what the mean scores are etc. More objective measures, because measurements (height, weight etc) should be the same no matter who is doing the measuring and therefore are reliable. This gives measures greater validity as they are not biased by the person doing the measuring.
What is a weakness of quantitative data?
-May not express participants precise thoughts/feelings because the answers provided are fixed so there may not be an answer to represent what they think. Therefore, data collected may be low in validity.
-Oversimplifies reality and human experience because it suggests that there are simple answers. It is a reductionist approach reducing human experience to quantities.
Define qualitative.
Information that is non-numerical prose.
What is a strength of qualitative data?
Represents the true complexities of human behaviour because thoughts and behaviours are not reduced to numbers. Therefore this is a holistic approach. Provides rich detail about how people think and behave as people are free to express themselves. Therefore this is higher in validity, as the researcher is more likely to be measuring the variable of interest.
What is a weakness of qualitative data?
-More difficult to detect patterns and draw conclusions because of the large variety of information collected and because words cannot be easily reduced to a few simple points.
-Interpreting what people think is likely to be subjective, lowering credibility.
Define closed questions.
Preset fixed answers- respondent much choose the answer that is the closest match to their opinion.
(Forced choice)
Describe the rating scale.
On a scale from 1 to 10
