What is a questionnaire?
Questionnaires involve a pre-set list of written questions (sometimes referred to as ‘items’) used to assess a person’s thoughts and/or experiences.
What is an open question?
Give an example
Respondent provides own answers expressed in words.
Example: Why did you start smoking?
This question would produce a range of personal answers.
Characteristics of open questions?
Allows a range of answers, thoughts, opinions etc.
Participants can answer in any way they like
Qualitative data
Lots of depth and detail
Can provide new ideas
Difficult to analyse
Strengths of open questions?
Responses are not restricted.
Answers more likely to provide detailed, unexpected information. Likely to have more external validity than statistics.
Limitations of open questions?
Difficult to analyse.
Wider variety of answers than produced by closed questions. May be forced to reduce data to statistics.
What is a closed question?
Give an example
Respondent has limited choices.
Example: How many cigarettes do you smoke a day? 0-10, 11-20, 21-30, 30+
This question would produce a range of personal answers
Characteristics of closed questions?
Fixed responses (e.g., yes or no)
Quantitative data
Quick and easy to analyse
Lack depth, detail and explanations
Strengths of closed questions?
Easier to analyse
Can produce graphs and charts for comparison. Makes it easier to draw conclusions.
Limitations of closed questions?
Responses are restricted
Forced into an answer that may not represent true feelings. May reduce the validity of the findings.
What are the types of closed questions?
Likert scales
Rating scales
Fixed choice option
What is an likert scale?
Give an example
The respondent indicates their agreement with a statement using a scale.
e.g. PE should be compulsory until the age of 18
1 2 3 4 5
Strongly agree To strongly disagree
What is a rating scale?
Give an example
The respondent identifies a value which represents their strength of feeling.
e.g. How much do you like PE?
1 2 3 4 5
Love like not bothered dislike hate
What is a fixed choice option?
Give an example
Includes a list of options that respondents choose
e.g. How often do you exercise?
Never
Once a year
Once a month
Once a day
Strengths of questionnaires
Can be distributed to lots of people
Gathers large amounts of data quickly and researcher need not be present when completed. This reduces the effort involved and makes questionnaires cost-effective.
Straightforward to analyse
Especially if closed, fixed-choice questions are used. The statistical data can easily be converted to graphs and charts for comparison.
Limitations of questionnaires?
Responses may not always be truthful
Respondents tend to present themselves in a positive light. Thus, social desirability bias is possible.
Response bias
Respondents may favour a particular kind of response, e.g., they always agree. This means that all respondents tend to reply in a similar way.
How can you write a good question?
Avoid jargon – use words the participants will understand
Avoid emotive language and leading questions
Avoid double barrelled questions – e.g., do you believe footballers are overpaid and should give 20% of their wage to charity?
Use a pilot study to check wording
What is an interview?
Interviews are ‘live’ encounters (e.g. face-to-face or over the phone) where the interviewer asks a set of questions to assess the participant’s thoughts and/or feelings.
What is a structured interview?
Questions are pre-set and asked in a fixed order
Easy to replicate
Can cause frustration for participants if they cannot elaborate on their points
Strengths of structured interviews?
Easy to replicate
Straightforward to replicate because of standardised format. The format also reduces differences between interviewers.
Limitations of structured interviews?
Interviewers cannot elaborate
Interviewers cannot deviate from the topic or explain their questions. This may limit the richness of data collected.
What is an unstructured interview?
No set questions
Ask questions in a free-flowing way
The direction of the interview can change depending on participants answers
Participants are encouraged to elaborate
Difficult to compare to other participant’s answers
Difficult to replicate
Strengths of unstructured interviews?
There is greater flexibility
Unlike a structured interview, point can be followed up as they arise. More likely to gain insight into interviewee’ worldview and collect unexpected information.
Limitations of unstructured interview?
Increased risk of interviewer bias.
Closer dialogue between interviewer and interviewee. Means more opportunity for unconscious cues.
What is a semi structured interview?
Questions are set beforehand, but the interviewer can follow up on questions when appropriate
