How to Write Effective Surveys
Designing surveys is easy; isn't it? The reality is that writing surveys is easy but writing surveys that will be effective is a little bit more difficult. The following are twenty tips that if followed will help you with your survey questionnaire design and help you write effective surveys.
1. What is the purpose of the survey?
There are many reasons for conducting questionnaires. By correctly phrasing the questions and structuring the answers surveys can be used in a multitude of ways and for a variety of reasons. When compiling a survey don't lose sight of its purpose.
2. Give the survey a good title
The survey title is an opportunity to instantly summarise a survey's objective and encourage respondents to participate. Respondents need to invest time in completing the survey so you need to encourage them that their investment will be worthwhile.
3. Ensure that you do not make the survey any longer than it needs to be
Every question that is asked should be asked for a reason. Minimize the questions providing you with 'nice to know' information and concentrate instead on the 'need to know' questions.
4. Use plain English, maintain consistency, avoid jargon and acronyms and don't ask questions that may result in ambiguous answers
Be careful when wording the question. If a question can be interpreted in more ways than one then there is a risk that any analysis of the survey results will be worthless or at the very least suspect.
5. Avoid long questions
Use short sentences wherever possible. Long questions can cause a respondent to lose concentration and lead to them abandoning the survey.
6. Ask only one question at a time
Avoid confusing the respondent with a question like 'Do you like golf and football?'
7. Do not influence the answer
Do not load the question. 'Should irresponsible shop keepers who sell tobacco to children be prosecuted?' is likely to have no value.
8. Ensure that the answer format used allows the respondent to answer the question being asked
Ensure that the respondent is able to answer how they really feel or they may be less inclined to complete the survey. As a last resort consider the benefit of including a "Don't know", "No comment" or similar response option.
9. While compiling your survey consider how you will want to analyse the results once the survey has been published
When asking questions that allow for a free text open ended response, such as when asking the respondent for their comments, appreciate that such information is likely to be difficult to score and/or summarised. Consider how answers can be grouped. For example "Indicate your length of service?" - 'less than 2 year', 'between 2 and 4 years' and 'more than 4'.
10. Try and ensure that the questionnaire flows
Group questions into clear categories as this will make it easier for the participants completing the survey.
11. Target your respondents carefully
In some cases you will want to target a specific group, in others a cross section. If you can't easily control the respondents consider including questions/answers that will allow you to filter out respondents that don't match your target profile.
12. Allow the respondent to expand on their answer or make comments
Allowing the respondent to make additional comments will increase their satisfaction level and will also give valuable feedback on the specific questions and/or the survey as a whole. Remember that for large sample collections it may prove difficult to analyze free text open ended responses.
13. If the survey you are conducting is to be confidential ensure that your pledge is upheld
If you have guaranteed the respondents that the survey is confidential ensure that the individual data is not to be shared with anyone and not used for any other purpose. Confidentiality must be maintained and any contact information deleted after the survey is complete.
14. Consider the advantages and disadvantages of allowing respondents to be anonymous or identifiable
If your respondents are to be anonymous then you will be unable to follow up or match "pre" or "post" surveys. There are advantages to allowing people to remain anonymous for example it would allow people to respond without possible peer pressure.
15. Consideration carefully the best response format
Maintaining a consistency in the format used for responses is good practice. When creating your survey keep in mind that when analyzing the data single selection radio buttons are easier to analyze than multiple selection check boxes. If a radio response can be used do not use a check box.
16. Provide the respondent with an estimate as to how much time the survey will take
Respondent drop out can increase if the survey appears to be a stream of never ending questions. It is good practice to give an indication as to how long the survey is likely to take so that the participants can choose the best time to complete the survey.
17. Provide respondents with the survey end date
Encourage respondents to complete the survey as soon as possible but advise respondents as to the survey’s end date so that they have the opportunity to schedule the necessary time.
18. Pilot the survey
Before publishing a live survey publish a small pilot survey to check for questions that are ambiguous or confusing and to ensure that the survey is aesthetically pleasing.
19. Before publishing the survey check the survey several times
Carefully check and then check again that the survey is grammatically correct and makes sense. If possible get someone else to proof read the survey before you publish, if you are unable to do this then take a break before checking again.
20. Remember to thank the respondent
To complete surveys respondents need to invest their time and they should be thanked at the end of completing the survey or in a follow up letter. You may even want to consider incentives such as a reward of some sort.
To get started there are numerous survey software websites to choose from.
