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 questionnaire 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. 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.
An important distinction is between open-ended and closed questions. 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 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.
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. Closed questions have been used to research type A personality e. They can be economical. This means they can provide large amounts of research data for relatively low costs. Therefore, a large sample size can be obtained which should be representative of the population, which a researcher can then generalize from. The questions are standardized.
All respondents are asked exactly the same questions in the same order. Instead, researchers will randomly select geographic areas for example, counties , then randomly select households within these areas. This creates a cluster sample, in which respondents are clustered together geographically. For example, a researcher may want to compare survey responses of African-Americans and Caucasians.
To ensure that there are enough Afrian-Americans in the survey, the researcher will first identify the African-Americans in the population and then randomly select a sample of African-Americans. Measurement error is the difference between the target population's characteristics and the measurement of these characteristics in a survey.
There are two types of measurement error: For example, a researcher may administer a survey about marital happiness.
However, some respondents may have had a fight with their spouse the evening prior to the survey, while other respondents' spouses may have cooked the respondent's favorite meal. The survey responses will be affected by the random day on which the respondents were chosen to participate in the study. With random error, the positive and negative influences on the survey measure balance out. Respondents should give informed consent before participating in a survey.
In order for respondents to give informed consent,. It is absolutely imperative that researchers keep respondents' identities confidential. To ensure confidentiality, researchers should not link respondents' identifiers to their survey responses when using data. Common identifiers include names, social security numbers, addresses, and telephone numbers. Anonymity is an even stronger safeguard of respondent privacy. If a researcher assures anonymity, it means that the researcher is unable to link respondents' names to their surveys.

Questionnaires can be classified as both, quantitative and qualitative method depending on the nature of questions. Specifically, answers obtained.
Survey research is a commonly used method of collecting information about a population of interest. There are many different types of surveys, several ways to administer them, and many methods .
Research Methods» Questionnaire. Questionnaire. By Saul McLeod, updated 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. The essence of survey method can be explained as “questioning individuals on a topic or topics and then describing their responses” (Jackson, , p).
This article shows a sample questionnaire with insert notes for every section. A field of applied statistics of human research surveys, survey methodology studies the sampling of individual units from a population and associated techniques of survey data collection, such as questionnaire construction and methods for improving the number and accuracy of responses to surveys. Survey methodology includes instruments or.
