Survey vs. Questionnaire: What’s the Difference and Which One Should You Use?
In this post, we’ll break down survey vs. questionnaire, explain how each works, and help you decide which one is best for your goals.
If you’ve ever wondered whether a survey and a questionnaire are the same thing, you’re not alone. The terms are often used interchangeably, but there’s actually a big difference between the two especially when it comes to how you collect and use feedback.
In this post, we’ll break down survey vs. questionnaire, explain how each works, and help you decide which one is best for your goals.
What is a questionnaire?
A questionnaire is a set of written questions used to collect information from people. It can be printed, emailed, or built into an online form. A questionnaire doesn’t do anything by itself, it just gathers responses.
Common use cases for questionnaires:
Collecting customer contact information
Basic feedback forms
Quick polls or preference checklists
Key takeaway: A questionnaire is just a list of questions. It doesn’t involve analysis or strategy, just data collection.
What is a survey?
A survey includes a questionnaire, but it also includes the process of distributing it, collecting responses, analyzing results, and drawing conclusions.
In other words, a survey is more than just questions; it's a full feedback loop designed to give you actionable insights.
Common use cases for surveys:
Customer satisfaction surveys (CSAT)
Market research surveys
Employee engagement surveys
Product feedback surveys
Key takeaway: A survey helps you turn responses into real data you can use to make smarter decisions.
