1 Numeracy & Quantitative Methods Laura Lake

2 Postal surveys or questionnaires are a form of self- completion or self-administered questionnaire. Self-completion: the researcher is not present as the questionnaire is being answered by the respondent. These can be delivered to respondents in a number of ways, usually: postal electronically e.g. via email Postal Surveys

3 How to design the delivery of a questionnaire – use self- completion or structured interview? Both are valid methods of collecting data from respondents with their own distinct advantages and disadvantages. Self-Completion as a Method of Collecting Survey Data

4 Resources in survey administration: cost and time Particularly with geographically dispersed respondents / accessing geographically remote respondents Implications for sample size. Respondent resources: time Able to complete at a time that is convenient for them. Advantages: Resources

5 Bias: mitigating some sources Interviewer effect – none. Interview variability – none. Implications for reliability and internal validity. Survey Topics & Anonymity Lack of interviewer – potential advantage with respondents who want to remain anonymous in order to give information about a sensitive subject. Advantages: Impact of Interviewers

6 Closed-questions: accuracy and ease of processing the data Standardisation of questions – impact for reliability Pre-coding and use of coding frames – impact on sources of error and intra-coder variability. Advantages: Question Formats

7 Access: meeting the needs of the sample of people responding to the survey appropriateness for people with reading difficulties / visual impairments formats for languages other than English Completion of Survey Little control over who completes the survey. What implications does this have for bias? Disadvantages: Access & Completion

8 Prompts: with self-completion no interviewer to help when respondents have difficulties answering questions wording of questions is particularly important – clear, unambiguous questions that are easy to understand and answer clear completion instructions Probes: with self-completion no interviewer to probe respondents to elaborate on their answers Implications for including an open-ended questions Disadvantages: Absence of an Interviewer

9 Closed-questions: limited chance for using open-ended questions No interviews for probes. Postal questionnaire: unlikely respondents will spend time writing lengthy responses. Ordering of questions: Self-completion means questionnaires can be read as a whole. Influence over respondent answers? Disadvantages: Question Formats

10 Questionnaire length Lengthy questionnaire generally not recommended. Respondent fatigue. Missing data No interviewer: greater potential for partial or non- answering of questions. Potential for not answering questions that are deemed no relevant by respondents. Disadvantages: Question Formats

11 Low response rate Postal surveys generally have a low rate of response when compared to interview-based surveys. Those who respond verses those who do not. Are those who respond those who have the most to say and what does this do in terms of bias for the data collected? Low response rate increases this risk. Disadvantages: Response Rate

12 Covering letter: purpose and importance of research, research funding, confidentiality and ethical considerations. Means of return: stamped address envelope Clarity of questionnaire instructions Attractive easy to follow design and layout Questionnaire length: keeping it short Question ordering: placement of interesting and sensitive questions Improving Response Rates?

13 Incentives? Follow-up strategy – may involve tracking. Tracking: determining whether each potential participant has responded or not. Used to: reduce time and cost expenditures of surveys by identifying and sending reminders to non-responders only. help differentiate the demographic characteristics of responders from non-responders identifying any duplication of responses. But, ethics? When surveying sensitive topic tracking may lower the response rates. Improving Response Rates?
