The Difference Between a Questionnaire and a Survey
Questionnaire and survey are terms often used interchangeably. In reality, they have different meanings. In this article, we explain the difference, when to use each, and how they can help companies better understand customers and markets.
There are many terms people use interchangeably, even though they actually mean different things. At first glance, they may sound similar, but upon closer examination, you’ll find their meaning and usage differ significantly. This is exactly the case with surveys and questionnaires. A survey refers to the entire research process — from defining the objective and designing questions to collecting, evaluating, and analyzing data. A questionnaire, on the other hand, is simply a tool — a set of questions used to gather information from respondents.
What is a survey?
If you’ve ever received an email with a short satisfaction questionnaire after an online purchase, you’ve likely already encountered a survey. A survey is a systematic process aimed at collecting data from a larger group of respondents. The survey is then analyzed, allowing companies to uncover connections, track changes in customer opinions, and identify new trends.
Surveys are used in a wide range of areas — for example, in market research, measuring customer satisfaction, tracking employee engagement, or analyzing demographic data.
Types of surveys
Customer satisfaction survey — Used to determine how satisfied customers are with a product, service, or specific experience. Most commonly measured using CSAT, NPS®, or CES metrics. Learn more about measuring on our customer experience page.
Market research survey — Helps companies understand their business environment. Focuses on competitor analysis, market opportunities, target audience behavior, and demand for new products.
Employee engagement survey — Measures how employees feel in the company and how motivated they are. Helps uncover team issues and improve company culture. Learn more about employee experience.
Pricing survey — Determines how customers perceive product or service pricing and how much they’re willing to pay.
Brand awareness survey — Focuses on whether your target audience knows your brand, how they perceive it, and what they associate it with.
Customer experience (CX) survey — Maps the entire customer journey from first brand contact to post-sale support.
Most common metrics
NPS® (Net Promoter Score®) — Measures how likely customers are to recommend your brand to others.
CSAT (Customer Satisfaction Score) — Measures overall satisfaction with a specific experience.
CES (Customer Effort Score) — Focuses on how easy it is for customers to perform a specific action.
What is a questionnaire?
You’ve probably filled out a satisfaction questionnaire after an online purchase, a service rating after a hotel stay, or a short questionnaire after contacting customer support. In such situations, you answer several questions designed to help the company better understand your experiences. Such a set of questions is a typical example of a questionnaire.
A questionnaire is a tool designed to collect information from respondents. It consists of pre-prepared questions that help organizations gather data for various purposes. Open-ended questions give respondents space to express their opinions in their own words. Closed-ended questions offer predefined answer options and enable data collection that can be easily compared and statistically evaluated.
Common questionnaire formats
Today, questionnaires are most commonly used online, allowing companies to quickly reach large numbers of respondents. Learn more on our online surveys page. Paper questionnaires are still used for in-person surveys, in schools, or at various events.
Questionnaire design
A well-designed questionnaire is the foundation of any quality research. If questions are unclear or poorly structured, they can lead to inaccurate or biased responses. The first step in creating a questionnaire is always clearly defining the objective and understanding the target audience of respondents.
Quantitative questionnaires work with closed-ended questions and predefined answers. Qualitative questionnaires contain open-ended questions. To yield meaningful data, it’s important to formulate questions simply, clearly, and without leading wording.
When to use a survey vs. a questionnaire
Use a questionnaire when you need to simply collect information from respondents. A questionnaire is a specific tool — a set of questions that people fill out.
Use a survey when you want to systematically analyze data and draw conclusions. A survey is a broader process that includes research design, data collection, analysis, and interpretation of results.
