All respondents are asked exactly the same questions in the same order. This means a questionnaire can be replicated easily to check for reliability. Therefore, a second researcher can use the questionnaire to check that the results are consistent. Because the responses are fixed, there is less scope for respondents to supply answers which reflect their true feelings on a topic. Open 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.
Rich qualitative data is obtained as open questions allow the respondent to elaborate on their answer. This means the research can find out why a person holds a certain attitude. Time-consuming to collect the data. It takes longer for the respondent to complete open questions. This is a problem as a smaller sample size may be obtained. Time-consuming to analyze the data.
It takes longer for the researcher to analyze qualitative data as they have to read the answers and try to put them into categories by coding, which is often subjective and difficult.
However, Smith has devoted an entire book to the issues of thematic content analysis the includes 14 different scoring systems for open-ended questions. Not suitable for less educated respondents as open questions require superior writing skills and a better ability to express one's feelings verbally. The researcher should ensure that the answer to a question is not influenced by previous questions. 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. The researcher must ensure that the information provided by the respondent is kept confidential, e. 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. The data might not be valid i. 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. Check that emotive questions have not been used as they make people defensive and could invalidate their answers. Ensure the questionnaire can be completed in an appropriate time frame i.

Survey methodology as a scientific field seeks to identify principles about the sample design, data collection instruments, statistical adjustment of data, and data processing, and final data analysis that can create systematic and random survey errors.
Survey errors are sometimes analyzed in connection with survey cost. Cost constraints are sometimes framed as improving quality within cost constraints, or alternatively, reducing costs for a fixed level of quality.
Survey methodology is both a scientific field and a profession, meaning that some professionals in the field focus on survey errors empirically and others design surveys to reduce them. For survey designers, the task involves making a large set of decisions about thousands of individual features of a survey in order to improve it.
The most important methodological challenges of a survey methodologist include making decisions on how to: The sample is chosen from the sampling frame, which consists of a list of all members of the population of interest.
This generalizing ability is dependent on the representativeness of the sample, as stated above. Each member of the population is termed an element.
There are frequent difficulties one encounters while choosing a representative sample. One common error that results is selection bias. Selection bias results when the procedures used to select a sample result in over representation or under representation of some significant aspect of the population.
In order to minimize selection biases, stratified random sampling is often used. This is when the population is divided into sub-populations called strata, and random samples are drawn from each of the strata, or elements are drawn for the sample on a proportional basis. There are several ways of administering a survey. The choice between administration modes is influenced by several factors, including. Different methods create mode effects that change how respondents answer, and different methods have different advantages.
The most common modes of administration can be summarized as: There are several different designs, or overall structures, that can be used in survey research. The three general types are cross-sectional, successive independent samples, and longitudinal studies. In cross-sectional studies, a sample or samples is drawn from the relevant population and studied once. A successive independent samples design draws multiple random samples from a population at one or more times.
Such studies cannot, therefore, identify the causes of change over time necessarily. For successive independent samples designs to be effective, the samples must be drawn from the same population, and must be equally representative of it. If the samples are not comparable, the changes between samples may be due to demographic characteristics rather than time.
In addition, the questions must be asked in the same way so that responses can be compared directly. Longitudinal studies take measure of the same random sample at multiple time points.
Longitudinal studies are the easiest way to assess the effect of a naturally occurring event, such as divorce that cannot be tested experimentally. However, longitudinal studies are both expensive and difficult to do. This attrition of participants is not random, so samples can become less representative with successive assessments. To account for this, a researcher can compare the respondents who left the survey to those that did not, to see if they are statistically different populations.
Respondents may also try to be self-consistent in spite of changes to survey answers. Questionnaires are the most commonly used tool in survey research.
However, the results of a particular survey are worthless if the questionnaire is written inadequately. A variable category that is often measured in survey research are demographic variables, which are used to depict the characteristics of the people surveyed in the sample.
Reliable measures of self-report are defined by their consistency. It is important to note that there is evidence to suggest that self-report measures tend to be less accurate and reliable than alternative methods of assessing data e. Six steps can be employed to construct a questionnaire that will produce reliable and valid results.
The way that a question is phrased can have a large impact on how a research participant will answer the question. A respondent's answer to an open-ended question can be coded into a response scale afterwards,  or analysed using more qualitative methods. Survey researchers should carefully construct the order of questions in a questionnaire. The following ways have been recommended for reducing nonresponse  in telephone and face-to-face surveys: Brevity is also often cited as increasing response rate.
A literature review found mixed evidence to support this claim for both written and verbal surveys, concluding that other factors may often be more important. Survey methodologists have devoted much effort to determining the extent to which interviewee responses are affected by physical characteristics of the interviewer. Main interviewer traits that have been demonstrated to influence survey responses are race,  gender,  and relative body weight BMI.
Hence, race of interviewer has been shown to affect responses to measures regarding racial attitudes,  interviewer sex responses to questions involving gender issues,  and interviewer BMI answers to eating and dieting-related questions. The explanation typically provided for interviewer effects is social desirability bias: Interviewer effects are one example survey response effects. From Wikipedia, the free encyclopedia.
Questionnaires can include the following types of questions: Open question questionnaires. Open questions differ from other types of questions used in questionnaires in a way that open questions may produce unexpected results, which can make the research more original and valuable.
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 .
