Steps in the Marketing Research Process

Step 3: Design the Data-Collection Forms

If the behavior of buyers is being formally observed, and a number of different researchers are conducting observations, the data obviously need to be recorded on a standardized data-collection form that's either paper or electronic. Otherwise, the data collected will not be comparable. The items on the form could include a shopper's sex; his or her approximate age; whether the person seemed hurried, moderately hurried, or unhurried; and whether or not he or she read the label on products, used coupons, and so forth.

The same is true when it comes to surveying people with questionnaires. Surveying people is one of the most commonly used techniques to collect quantitative data. Surveys are popular because they can be easily administered to large numbers of people fairly quickly. However, to produce the best results, the questionnaire for the survey needs to be carefully designed.

Questionnaire Design

Most questionnaires follow a similar format: They begin with an introduction describing what the study is for, followed by instructions for completing the questionnaire and, if necessary, returning it to the market researcher. The first few questions that appear on the questionnaire are usually basic, warm-up type of questions the respondent can readily answer, such as the respondent's age, level of education, place of residence, and so forth. The warm-up questions are then followed by a logical progression of more detailed, in-depth questions that get to the heart of the question being researched. Lastly, the questionnaire wraps up with a statement that thanks the respondent for participating in the survey and information and explains when and how they will be paid for participating.

How the questions themselves are worded is extremely important. It's human nature for respondents to want to provide the "correct" answers to the person administering the survey, so as to seem agreeable. Therefore, there is always a hazard that people will try to tell you what you want to hear on a survey. Consequently, care needs to be taken that the survey questions are written in an unbiased, neutral way. In other words, they shouldn't lead a person taking the questionnaire to answer a question one way or another by virtue of the way you have worded it. The following is an example of a leading question.

Don't you agree that teachers should be paid more?

The questions also need to be clear and unambiguous. Consider the following question:

Which brand of toothpaste do you use?

The question sounds clear enough, but is it really? What if the respondent recently switched brands? What if she uses Crest at home, but while away from home or traveling, she uses Colgate's Wisp portable toothpaste-and-brush product? How will the respondent answer the question? Rewording the question as follows so it's more specific will help make the question clearer:

Which brand of toothpaste have you used at home in the past six months? If you have used more than one brand, please list each of them".

Sensitive questions have to be asked carefully. For example, asking a respondent, "Do you consider yourself a light, moderate, or heavy drinker?" can be tricky. Few people want to admit to being heavy drinkers. You can "soften" the question by including a range of answers, as the following example shows:

How many alcoholic beverages do you consume in a week?

  • 0–5 alcoholic beverages
  • 5–10 alcoholic beverages
  • 10–15 alcoholic beverages

Many people don't like to answer questions about their income levels. Asking them to specify income ranges rather than divulge their actual incomes can help.

Other research question "don'ts" include using jargon and acronyms that could confuse people. "How often do you IM?" is an example. Also, don't muddy the waters by asking two questions in the same question, something researchers refer to as a double-barreled question. "Do you think parents should spend more time with their children and/or their teachers?" is an example of a double-barreled question.

Open-ended questions, or questions that ask respondents to elaborate, can be included. However, they are harder to tabulate than closed-ended questions, or questions that limit a respondent's answers. Multiple-choice and yes-and-no questions are examples of closed-ended questions.


Testing the Questionnaire

You have probably heard the phrase "garbage in, garbage out". If the questions are bad, the information gathered will be bad, too. One way to make sure you don't end up with garbage is to test the questionnaire before sending it out to find out if there are any problems with it. Is there enough space for people to elaborate on open-ended questions? Is the font readable? To test the questionnaire, marketing research professionals first administer it to a number of respondents face to face. This gives the respondents the chance to ask the researcher about questions or instructions that are unclear or don't make sense to them. The researcher then administers the questionnaire to a small subset of respondents in the actual way the survey is going to be disseminated, whether it's delivered via phone, in person, by mail, or online.

Getting people to participate and complete questionnaires can be difficult. If the questionnaire is too long or hard to read, many people won't complete it. So, by all means, eliminate any questions that aren't necessary. Of course, including some sort of monetary incentive for completing the survey can increase the number of completed questionnaires a market researcher will receive.
