Introduction
This web-page is organised into the following sections:Questionnaires and interviews share a
common purpose and can be considered as alternative ways of collecting the same
information. Indeed in their simplest form the only differences between them are that:
i) A questionnaire is written and
the interview a spoken series of questions.
ii) Limited, if any, interaction can take place in
questionnaires.
iii) Greater confidentiality is possible with questionnaires
- the researcher can organise the
questionnaire so that she/he
does not know who gave a particular response.
The information given below recommends an
eclectic questionnaire sharing aspects of both empirical research
paradigms:

Scientific Paradigm |
Socio-Anthropological Paradigm |
Questionnaires |
Multiple-choice/Attitude Closed questions* |
Open-ended-questions*, Essays Diaries etc. |
* The differences between open-ended and closed-ended questions are
two-fold. Open-ended questions:
i) allow the interviewee to reply using their own words and ii) enable a
wider range of possible responses to be given.
Since questionnaires are inflexible and a relative bore to complete it is essential to encourage the respondent by both explaining why it is worth filling in the questionnaire and making it attractive, easy to fill in and quick to complete.
Hence, before any questions are written, consider carefully:
a) the purpose of the questionnaire i.e. it's research
aims
b) list ideas in order of priority
c) how the questionnaire is to be analysed.
Hence many of the guidelines below are related to making questionnaires easy to fill in and quick to complete.
| a)
|
Make the questionnaire as short as practicable: Unless the responders are very committed, or captive (a class of students) aim at a maximum of 5 to 10 rather than 20 to 30 minutes. It is self evident that there must be an inverse relationship between the length of the questionnaire and the percentage of returns obtained. |
| b)
|
Number the questions: N.B. The collation of responses, on to a database, is quicker and more accurate, when one person reads the information and another enters it - coding the questionnaire makes this and later cross-checking much easier. |
| c)
|
Pilot the questionnaire: There is no such thing as a perfect questionnaire. Put the draft on one side for a few days and then try to answer it. Ask your dissertation/thesis supervisor and relevant colleagues to read the questionnaire to help ensure that you have asked relevant questions. Pilot it with a group of comparable individuals to check that the questions are clear and provide the range of feedback that you expect. |
| d) |
Dont give respondents too much time to fill in the questionnaire: i.e. dont distribute it and ask for it back in a month. If the questionnaire is not answered quickly the probability is that it will be put down and lost. |
| e)
|
Ensure the questionnaire looks attractive and is easy to fill in: For example, with open-ended questions dont draw lines telling the respondent how much they should write. The additional advantage of a blank space is that respondents can write small if they wish to give a very full answer. | ||||
| f) | Introduce the questionnaire clearly: Explain its purpose and make it interesting to the potential respondent. | ||||
| g)
|
Give clear information on how the questionnaire is to be returned: If it is posted either arrange collection or include a stamped addressed envelope. Try and keep a check on who has replied so that if the response rate is low, you have some chance of discovering why. - But, as a point of ethics, if you have promised TOTAL confidentiality, then: | ||||
|
|||||
| h) |
Report the findings back: Apart from being simply good manners, it is also essential research practice if you subsequently wish to question/interview those same individuals again. Top of the Page |
| a)
|
Questions Must ReferTo A Single Aspect. The major underlying weakness of questionnaires is that neither the researcher nor the respondent can ask for clarification, this means that it is crucial for questions to be as clear and simple as possible. The normal mechanism to ensure this to use short multiple choice questions wherever practicable. |
| b)
|
Questions Must Be Unambiguous: if a question can be misunderstood or mis-interpreted it will be! Whereas in an interview it can be productive to start by asking questions which are very general, the danger in a questionnaire is that such questions will produce an equally general :responses What do you think of the XXXXX? Responses such as not much, OK might let the course organiser know if there are any problems, but they dont provide the information needed to improve the course. | ||||||||||||||||

Consider The Type of Question Which Will Best
Obtain The Information Required: many questions which appear to be open-ended
can be converted into a multiple choice
format: Questions such as How many students attend your
institution? rarely need a detailed response like 1,563. Instead
begin the analysis process. How is the information going to be used? All that
might be required is a decision on whether the institution is small medium or
large; hence think about size and
provide a range of answers such as: Less than 600 children 601 to 1200 children More than 1200 children |
||||||||||||||||
| d)
|
Multiple Choice Questions Must Have
Exclusive Categories. With the use of number categories such as
those given above and age, this is widely recognised eg. age:
7 to 11 years old 11 to 16 years old an eleven
year old could select either category. Be particularly careful of descriptive
categories, like those illustrated by Gilbert (1981 p10), where the categories may
not be mutually exclusive (compare 2 and 6, and 3 and 5): .The major reason for mothers with children choosing to go out to work
|
||||||||||||||||
| e) |
Multiple Choice Questions must be Exhaustive. This is normally done by including an 'other' category and asking for it to be clarified. Top of the Page | ||||||||||||||||
| a)
|
Multiple choice identification questions:
Remember, if you intend to compare the responses of different groups of people, then it is
essential to include questions which will identify the groups i.e. consider:
|
||||
| b)
|
Multiple choice information questions.
Consider which type of question will give you the information required. Many
questions which appear to be open-ended can be easily converted into a multiple
choice format. Questions such as How many students attend your institution? appear to be expecting a detailed response like 1,563; if all that is required is information on whether the institution is large or small it is better to offer a range of classifications. |
||||
| c)
|
Multiple choice attitude statements/questions. The value of these questions is that they can quickly obtain information on a wide range of topics. Essential questions in factor or cluster analysis is going to be considered. These questions are generally described as having a Likert-style response. Strongly recommend a six category rather than a five category response, i.e. from either: Strongly Disagree to Strongly Agree, or NO! to YES!, because both can be analysed with two and three categories. See tables below. |

Table 2 has far more information in it than would normally be recommended, but it illustrates how the 6 category responses (lime coloured) can be reorganised into three and two categories (yellow and blue respectively). The latter being far easier to describe.
The statistical debate with respect to attitude questions is whether the numerical value is ordinal or interval. Mathematicans would almost certainly state they were ordinal, but the linguistic logic is that they have interval aspects. The range of responses can be considered as a continuous range of views, from Strongly Disagree to Strongly Agree, or NO! to YES!: (see table 1 above and discussion ordinal or interval). Indeed, in some questionnaires the interval aspect is emphasised by representing the continuum as a line, divided into points of equal length. Statistically, the present writer, has regularly found that they can be meaningfully interpreted effectively using factor and cluster analyses, both of which theoretically require interval data.

Always ask at least one open-ended question:
(socio-anthropologists would request far more). Give the responders the opportunity
to tell you what they think. Incidentally, apart from invariably providing new
insights quotations from such questions also help make the final dissertation/thesis much
more interesting to read. However, whilst it can be productive in an interview to initially ask very general questions, the danger in a questionnaire is that such questions will produce an equally general responses:
|
| e)
|
Other types
questions e.g. Osgood's semantic differential - respondent is presented with a range of alternative words and asked to circle the one(s) which 'best' answer the question. e.g. A teacher is like a: parent, policeman, friend, boss, helper, colleague, dictator, sergeant-major
Order questions - rank order the following statements, giving 1 to the most important. If the statement is irrelevant leave the order box blank, if two statements are equally important give them the same order number... |
IV. Strengths of Questionnaires:
They SAVE TIME by allowing:
| a) | a large number of individuals to be questioned without excessive use of the evaluators time. |
| b)
|
each individual to quickly provide detailed information of their views. Both questionnaires and interviews provide the individual feedback that is inevitably lost at staff meetings, where information from particular individuals can be non-existent |
| c) | rapid analysis and feedback. |
They ENCOURAGE OBJECTIVITY:
| d)
|
Questionnaires are the only data collecting method where total confidentiality, even from the researcher, can be guaranteed. - this means that individuals can give their views strongly without affecting relationships - or career prospects! | ||||
| e) | All questions are presented in an identical fashion. | ||||
Researcher bias can be checked in advance through procedures such
as:
|
|||||
| f) | The researcher is encouraged to plan each question carefully. With such in-depth planning researchers are more likely to consider how the information gained is to be analysed. |
| a)
|
Questionnaires are inflexible: It is virtually impossible to interrogate the respondent. Difficult to clarify some question responses. The researcher sometimes has a problem in analysing an open-ended questionnaire response: Single words can be particularly difficult to classify: sarcastically could "FASCINATING!" mean the converse?. Questions have to be very carefully worded - As a regular user of questionnaires I have found that, where it is possible for a question to be misunderstood, it will be! (In an interview such errors can usually be clarified.) Questionnaires suffer from user-unfriendliness. Most individuals seem to find questionnaires boring, they would much rather answer such questions face to face. Questionnaires cannot smile, answer new questions or apologise! Hence: |

VI. Response Rate Acceptable response rate = 60%
The literature is over-critical with respect to the response rate to questionnaires because they fail to state that the questionnaires they are referring to are of a survey nature. The response rate to a clearly defined group, particularly one known to the researcher, is commonly high: how many children in a class, colleagues in a school are likely to refuse to fill in a questionnaire for a teacher or colleague? Even with some surveys, the response rate can be very high:

|||
A low response rate is likely when:
| a)
|
Too many open-ended questions are asked and the
questionnaire is long. Open-ended questions are particularly
appealing to recipients because they demonstrate that any response is acceptable.
However, too many of them and the likelihood will be that the
questionnaire is put on one side to be returned to later or never! Hence,
when possible, use a majority of Closed-ended questions.
|
||||||||||
| b)
|
Unless a questionnaire is filled in immediately it is VERY EASY TO MISPLACE. If the response rate is low, try to discover why. Study the identification questions to see if the sample appears to be a fair one. Send out reminder letters. IF the response remains low, use the data BUT state clearly the problem and be very wary of making any generalisations. | ||||||||||
VII. Organising Questionnaire Data for Analysis
The writer strongly recommends the
use of Microsoft EXCEL
for entering and initially analysing
questionnaire responses. The major reasons for this are that the database:
N.B. the descriptions record and field do not appear on the screen
Fields can be altered in size (use mouse or Alt F & W). In the example below, field A has been made slightly smaller, fields B to K reduced and field L increased in size. Some spreadsheets/databases, e.g. EXCEL, can also make the records narrower or deeper.

With spreadsheets like EXCEL the Fields cannot be labelled, in spreadsheets the
first row is used to identify the columns AND the Split command (ALT W and S)
to create the following impression:

Because of the possibility of using SPSS, it is worth also doing this with EXCEL .
Finally, in case you ever intend to analyse your data using SPSS, ensure that the field names in spreadsheets begin with a LETTER, have a maximum of 8 characters and don't include hyphens, full stops etc. Top of the Page
Initial analysis of closed ended questions (multiple choice/attitude questions/statements) can be done using specially prepared spreadsheets see QuestAnal-6.xls and Questanal-5.XLS both of which provide a rapid detailed overview, Dataanal.xls can be used but is more cumbersome, all have been prepared by Graham Tall and can be found on the following web page: Chi test . For detailed analyses at MPhil/PhD level SPSS will often be necessary. See Analysis Closed Ended Data
Analysing open ended questions can be done
using Microsoft WORKS database or, NUDIST. See:
Open Ended Analysis
