Sometimes it is very difficult for a researcher to gain all of the necessary information through observations alone. Along with his observations of the dining halls, Derek wanted to know what students ate in a typical day, and so he used a survey to have them keep track of their eating habits. Likewise, Jared wanted to learn about writing and communication in engineering and decided to draw upon expert knowledge by asking experienced individuals within the field.

Interviews and surveys are two ways that you can gather information about people’s beliefs or behaviors. With these methods, the information you collect is not first-hand (like an observation) but rather “self-reported” data, or data collected in an indirect manner. William Shadish, Thomas Cook, and Donald Campbell argued that people are inherently biased about how they see the world and may report their own actions in a more favorable way than they may actually behave. Despite the issues in self-reported data, surveys and interviews are an excellent way to gather data for your primary research project

Survey or Interview?

How do you choose between conducting a survey or an interview? It depends on what kind of information you are looking for. You should use surveys if you want to learn about a general trend in people’s opinions, experiences, and behavior. Surveys are particularly useful to find small amounts of information from a wider selection of people in the hopes of making a general claim. Interviews are best used when you want to learn detailed information from a few specific people. Interviews are also particularly useful if you want to interview experts about their opinions, as Jared did. In sum, use interviews to gain details from a few people, and surveys to learn general patterns from many people.

Writing Good Questions

One of the greatest challenges in conducting surveys and interviews is writing good questions. As a researcher, you are always trying to eliminate bias, and the questions you ask need to be unbiased and clear. Here are some suggestions on writing good questions:

Ask about One Thing at a Time

A poorly written question can contain multiple questions, which can confuse participants or lead them to answer only part of the question you are asking. This is called a “double-barreled question” in journalism. The following questions are taken from Jared’s research:

Poor question: What kinds of problems are being faced in
the field today and where do you see the search for solutions
to these problems going?

Revised question #1 : What kinds of problems are being
faced in the field today?

Revised question #2: Where do you see the search for solutions
to these problems going?

Avoid Leading Questions

A leading question is one where you prompt the participant to respond in a particular way, which can create bias in the answers given:

Leading question: The economy is clearly in a crisis,
wouldn’t you agree?

Revised question: Do you believe the economy is currently
in a crisis? Why or why not?

Understand When to Use Open and Closed Questions

Closed questions, or questions that have yes/no or other limited responses, should be used in surveys. However, avoid these kinds of questions in interviews because they discourage the interviewee from going into depth. The question sample above, “Do you believe the economy currently is in a crisis?” could be answered with a simple yes or no, which could keep a participant from talking more about the issue. The “why or why not?” portion of the question asks the participant to elaborate. On a survey, the question “Do you believe the economy currently is in a crisis?” is a useful question because you can easily count the number of yes and no answers and make a general claim about participant responses.

Write Clear Questions

When you write questions, make sure they are clear, concise, and to the point. Questions that are too long, use unfamiliar vocabulary, or are unclear may confuse participants and you will not get quality responses.

Now that question creation has been addressed, we will next examine specific considerations for interviews and surveys.
