A questionnaire is a research instrument consisting of a series of questions for the purpose of gathering information from respondents. Questionnaires can be thought of as a kind of written interview. They can be carried out face to face, by telephone, computer or post. Questionnaires provide a relatively cheap, quick and efficient way of obtaining large amounts of information from a large sample of people. Data can be collected relatively quickly because the researcher would not need to be present when the questionnaires were completed. This is useful for large populations when interviews would be impractical. However, a problem with questionnaires is that respondents may lie due to social desirability. Most people want to present a positive image of themselves and so may lie or bend the truth to look good, e.g., pupils would exaggerate revision duration. Questionnaires can be an effective means of measuring the behavior, attitudes, preferences, opinions and, intentions of relatively large numbers of subjects more cheaply and quickly than other methods. Often a questionnaire uses both open and closed questions to collect data. This is beneficial as it means both quantitative and qualitative data can be obtained. Closed QuestionsClosed questions structure the answer by only allowing responses which fit into pre-decided categories. Data that can be placed into a category is called nominal data. The category can be restricted to as few as two options, i.e., dichotomous (e.g., 'yes' or 'no,' 'male' or 'female'), or include quite complex lists of alternatives from which the respondent can choose (e.g., polytomous). Closed questions can also provide ordinal data (which can be ranked). This often involves using a continuous rating scale to measure the strength of attitudes or emotions. For example, strongly agree / agree / neutral / disagree / strongly disagree / unable to answer. Closed questions have been used to research type A personality (e.g., Friedman & Rosenman, 1974), and also to assess life events which may cause stress (Holmes & Rahe, 1967), and attachment (Fraley, Waller, & Brennan, 2000).

Open QuestionsOpen questions allow people to express what they think in their own words. Open-ended questions enable the respondent to answer in as much detail as they like in their own words.
If you want to gather more in-depth answers from your respondents, then open questions will work better. These give no pre-set answer options and instead allow the respondents to put down exactly what they like in their own words. Open questions are often used for complex questions that cannot be answered in a few simple categories but require more detail and discussion. Lawrence Kohlberg presented his participants with moral dilemmas. One of the most famous concerns a character called Heinz who is faced with the choice between watching his wife die of cancer or stealing the only drug that could help her. Participants were asked whether Heinz should steal the drug or not and, more importantly, for their reasons why upholding or breaking the law is right. Strengths

Questionnaire DesignWith some questionnaires suffering from a response rate as low as 5%, it is essential that a questionnaire is well designed. There are a number of important factors in questionnaire design. AimsMake sure that all questions asked address the aims of the research. However, use only one feature of the construct you are investigating in per item. LengthThe longer the questionnaire, the less likely people will complete it. Questions should be short, clear, and be to the point; any unnecessary questions/items should be omitted. Pilot StudyRun a small scale practice study to ensure people understand the questions. People will also be able to give detailed honest feedback on the questionnaire design. Question OrderQuestions should progress logically from the least sensitive to the most sensitive, from the factual and behavioral to the cognitive, and from the more general to the more specific. The researcher should ensure that the answer to a question is not influenced by previous questions. TerminologyThere should be a minimum of technical jargon. Questions should be simple, to the point and easy to understand. The language of a questionnaire should be appropriate to the vocabulary of the group of people being studied. Use statements which are interpreted in the same way by members of different subpopulations of the population of interest. For example, the researcher must change the language of questions to match the social background of respondents' age / educational level / social class / ethnicity etc. PresentationMake sure it looks professional, include clear and concise instructions. If sent through the post make sure the envelope does not signify ‘junk mail.’ Ethical IssuesThe researcher must ensure that the information provided by the respondent is kept confidential, e.g., name, address, etc. This means questionnaires are good for researching sensitive topics as respondents will be more honest when they cannot be identified. Keeping the questionnaire confidential should also reduce the likelihood of any psychological harm, such as embarrassment. Participants must provide informed consent prior to completing the questionnaire, and must be aware that they have the right to withdraw their information at any time during the survey/ study. Problems with Postal QuestionnairesThe data might not be valid (i.e., truthful) as we can never be sure that the right person actually completed the postal questionnaire. Also, postal questionnaires may not be representative of the population they are studying?
Benefits of a Pilot StudyA pilot study is a practice / small-scale study conducted before the main study. It allows the researcher to try out the study with a few participants so that adjustments can be made before the main study, so saving time and money. It is important to conduct a questionnaire pilot study for the following reasons:

It is ideal for studying large numbers of people. The survey is the most widely used research method for collecting data in sociology.
What research method is effective in gathering large amounts of data?Questionnaires and surveys
This can be useful if you're collecting a large amount of data from a large population. To be meaningful, surveys and questionnaires need to be carefully planned.
Which research design includes gathering data over a long period of time?In a longitudinal study, researchers repeatedly examine the same individuals to detect any changes that might occur over a period of time. Longitudinal studies are a type of correlational research in which researchers observe and collect data on a number of variables without trying to influence those variables.
Which research method is best suitable when the area of research will be large?The correct method is Census Method.
It also refers to as the complete survey method.
