The one-to-one interview helps researchers gather information or data directly from a respondent. These interviews can last from 30 minutes up to a few hours. These surveys are administered to a small sample from a larger population within a small time frame. This type offers a researcher a quick summary of what respondents think at that given time.
These surveys are short and ready to answer and can measure opinion in one particular situation. Consider hypothetically, an organization conducts a study related to breast cancer in America, and they choose a sample to obtain cross-sectional data. This data indicated that breast cancer was most prevalent in women of African-American origin. The information is from one point in time. Learn more: Cross-sectional Study. Longitudinal surveys are those surveys that help researchers to make an observation and collect data over an extended period.
There are three main types of longitudinal studies: trend surveys, panel surveys, cohort surveys. Trend surveys are deployed by researchers to understand the shift or transformation in the thought process of respondents over some time. Another longitudinal survey type is a panel survey. Researchers administer these surveys to the same set or group of people over the years.
Panel surveys are expensive in nature and researchers to try to stick to their panel to gather unbiased opinions. The third type of longitudinal survey is the cohort survey. In this type, categories of people that meet specific similar criteria and characteristics form the target audience.
However, people forming a group should have certain similarities. Learn more: Longitudinal Study. A retrospective survey is a type of study in which respondents answer questions to report on events from the past. By deploying this kind of survey, researchers can gather data based on past experiences and beliefs of people.
This way, they can save the cost and time required, unlike a longitudinal survey. Learn more: Cross-sectional vs Longitudinal Study. When an agency needs reliable, projectable data about the attitudes and opinions of its citizens or a select group of its citizens, it is essential to conduct a valid, random sample survey.
Telephone interview surveys are considerably more common than in-person interviews because they are far less expensive to administer and act as a standard tool for gathering information. There is a margin of error, based upon the size of the sample generally, a minimum population sample of is the industry standard for reliable data about any population segment.
Overall, random sample telephone interview surveys provide reasonably accurate information about the population. A random sample survey is not appropriate for educating people about an issue or trying to assess what people will do at some future point i.
If you are trying to calculate the ideal margin of error for your research, you can use tools like our margin of error calculator. When an agency has a political need to create a survey process that allows anyone interested in responding, it can do a self-selected process.
A written survey can be distributed in public locations, such as the City Hall or Library, emailed directly, emailed, or published in the city newsletter or the local newspaper.
A self-selected survey can be an excellent public relations tool and the right way of giving information to the public. Learn more: Research Design. A researcher must have a proper medium to conduct research and collect meaningful information to make informed decisions. Also, it is essential to have a platform to create and deploy these various types of market research surveys.
QuestionPro is a platform that helps not only to create but also to deploy different types of surveys. In the online survey world, mastery of all three can lead to sounder insights and greater quality information. Exploratory research is an important part of any marketing or business strategy. Its focus is on the discovery of ideas and insights as opposed to collecting statistically accurate data. That is why exploratory research is best suited as the beginning of your total research plan.
It is most commonly used for further defining company issues, areas for potential growth, alternative courses of action, and prioritizing areas that require statistical research.
Looking for the right audience to test your ideas on? When it comes to online surveys, the most common example of exploratory research takes place in the form of open-ended questions. Think of the exploratory questions in your survey as expanding your understanding of the people you are surveying.
Text responses may not be statistically measureable, but they will give you richer quality information that can lead to the discovery of new initiatives or problems that should be addressed. Descriptive research takes up the bulk of online surveying and is considered conclusive in nature due to its quantitative nature. Unlike exploratory research, descriptive research is preplanned and structured in design so the information collected can be statistically inferred on a population.
The main idea behind using this type of research is to better define an opinion, attitude, or behaviour held by a group of people on a given subject. Consider your everyday multiple choice question.
Since there are predefined categories a respondent must choose from, it is considered descriptive research. These questions will not give the unique insights on the issues like exploratory research would.
Instead, grouping the responses into predetermined choices will provide statistically inferable data. Send your survey to a large or small group of people with our online Audience panel.
This method has since become a very popular method for quantitative research in the social sciences. The survey method can be used for descriptive, exploratory, or explanatory research. This method is best suited for studies that have individual people as the unit of analysis.
Survey research has several inherent strengths compared to other research methods. Second, survey research is also ideally suited for remotely collecting data about a population that is too large to observe directly. A large area, such as an entire country, can be covered using mail-in, electronic mail, or telephone surveys using meticulous sampling to ensure that the population is adequately represented in a small sample.
Fourth, interviews may be the only way of reaching certain population groups such as the homeless or illegal immigrants for which there is no sampling frame available. Fifth, large sample surveys may allow detection of small effects even while analyzing multiple variables, and depending on the survey design, may also allow comparative analysis of population subgroups i. Sixth, survey research is economical in terms of researcher time, effort and cost than most other methods such as experimental research and case research.
At the same time, survey research also has some unique disadvantages. It is subject to a large number of biases such as non-response bias, sampling bias, social desirability bias, and recall bias, as discussed in the last section of this chapter. Depending on how the data is collected, survey research can be divided into two broad categories: questionnaire surveys which may be mail-in, group-administered, or online surveys , and interview surveys which may be personal, telephone, or focus group interviews.
Questionnaires are instruments that are completed in writing by respondents, while interviews are completed by the interviewer based on verbal responses provided by respondents. Invented by Sir Francis Galton, a questionnaire is a research instrument consisting of a set of questions items intended to capture responses from respondents in a standardized manner. Questions may be unstructured or structured. Unstructured questions ask respondents to provide a response in their own words, while structured questions ask respondents to select an answer from a given set of choices.
Questions should be designed such that respondents are able to read, understand, and respond to them in a meaningful way, and hence the survey method may not be appropriate or practical for certain demographic groups such as children or the illiterate.
Most questionnaire surveys tend to be self-administered mail surveys , where the same questionnaire is mailed to a large number of people, and willing respondents can complete the survey at their convenience and return it in postage-prepaid envelopes. Mail surveys are advantageous in that they are unobtrusive, and they are inexpensive to administer, since bulk postage is cheap in most countries.
However, response rates from mail surveys tend to be quite low since most people tend to ignore survey requests. Hence, the researcher must continuously monitor responses as they are being returned, track and send reminders to non-respondents repeated reminders two or three reminders at intervals of one to 1. Questionnaire surveys are also not well-suited for issues that require clarification on the part of the respondent or those that require detailed written responses.
Longitudinal designs can be used to survey the same set of respondents at different times, but response rates tend to fall precipitously from one survey to the next. A second type of survey is group-administered questionnaire.
A sample of respondents is brought together at a common place and time, and each respondent is asked to complete the survey questionnaire while in that room. Respondents enter their responses independently without interacting with each other.
This format is convenient for the researcher, and high response rate is assured. If respondents do not understand any specific question, they can ask for clarification. In many organizations, it is relatively easy to assemble a group of employees in a conference room or lunch room, especially if the survey is approved by corporate executives. A more recent type of questionnaire survey is an online or web survey. These surveys are administered over the Internet using interactive forms.
Respondents may receive an electronic mail request for participation in the survey with a link to an online website where the survey may be completed. Alternatively, the survey may be embedded into an e-mail, and can be completed and returned via e-mail. These surveys are very inexpensive to administer, results are instantly recorded in an online database, and the survey can be easily modified if needed.
However, if the survey website is not password-protected or designed to prevent multiple submissions, the responses can be easily compromised. Furthermore, sampling bias may be a significant issue since the survey cannot reach people that do not have computer or Internet access, such as many of the poor, senior, and minority groups, and the respondent sample is skewed toward an younger demographic who are online much of the time and have the time and ability to complete such surveys.
Computing the response rate may be problematic, if the survey link is posted on listservs or bulletin boards instead of being e-mailed directly to targeted respondents. For these reasons, many researchers prefer dual-media surveys e. Constructing a survey questionnaire is an art. Numerous decisions must be made about the content of questions, their wording, format, and sequencing, all of which can have important consequences for the survey responses.
Response formats. Survey questions may be structured or unstructured. Responses to structured questions are captured using one of the following response formats:.
Question content and wording. Responses obtained in survey research are very sensitive to the types of questions asked. Poorly framed or ambiguous questions will likely result in meaningless responses with very little value.
Dillman recommends several rules for creating good survey questions. Every single question in a survey should be carefully scrutinized for the following issues:. Question sequencing. In general, questions should flow logically from one to the next. To achieve the best response rates, questions should flow from the least sensitive to the most sensitive, from the factual and behavioral to the attitudinal, and from the more general to the more specific.
Some general rules for question sequencing:. Other golden rules. Do unto your respondents what you would have them do unto you.
Always practice the following strategies for all survey research:. Interviews are a more personalized form of data collection method than questionnaires, and are conducted by trained interviewers using the same research protocol as questionnaire surveys i.
However, unlike a questionnaire, the interview script may contain special instructions for the interviewer that is not seen by respondents, and may include space for the interviewer to record personal observations and comments. In addition, unlike mail surveys, the interviewer has the opportunity to clarify any issues raised by the respondent or ask probing or follow-up questions. However, interviews are time-consuming and resource-intensive.
Special interviewing skills are needed on part of the interviewer. The interviewer is also considered to be part of the measurement instrument, and must proactively strive not to artificially bias the observed responses.
