19 Qualities of a Good Questionnaire

Questionnaires can be a great way to gather data from a large group of people, but they can also be time-consuming and confusing to design. In this article, we will go over some qualities of a good questionnaire, which makes them easy for your respondents to complete.

What is a Questionnaire? 

A questionnaire is a tool used to collect data from a group of people. It is usually used in survey research to collect information about a particular topic. Questionnaires can be brief or lengthy, and they can be administered in person, online, or by phone. 

There are many different types of questionnaires, and each has its own specific advantages and disadvantages. Some questionnaires are more sensitive than others, and some are better at assessing complex topics. 

Questionnaires can be very useful for collecting data about a variety of subjects. They can be used to study consumer behavior, attitudes, and preferences. They can also be used to gather information about the health and well-being of people. 

Types of Questionnaires 

There are a few different types of questionnaires that can be used in research. 

  1. Closed-ended questionnaire:
    This type of questionnaire has a set number of questions, and the respondent is not allowed to write in their own responses. 
  2. Open-ended questionnaire:
    This type of questionnaire allows respondents to write in their own responses, which can make it more difficult to collect data. However, this type of questionnaire can also be more useful because it allows respondents to express their thoughts and feelings freely.
  3. Semi-open-ended questionnaire:
    This type of questionnaire has a set number of questions, but some questions are left open for respondents to answer in their own way. This can help to gather more detailed information about the respondent’s thoughts and feelings. 

Once you have decided on the type of questionnaire that will be used in your research, it is important to consider the target audience. Questionnaires can be designed specifically for either respondents or researchers. If the questionnaire is designed specifically for respondents, it may need to be shortened or simplified so that it is easy to understand. If the questionnaire is designed specifically for researchers, it may be more detailed and difficult to use.
