Dichotomous questions are the simplest questions you can put in a survey: each one has only two possible answers. You have almost certainly answered one today, for example “Have you used our app before?” Yes / No.

They look basic, but they do a lot of work. They filter respondents, power skip logic and give you data that is easy to count. In this guide you will learn what a dichotomous question is, the six main types, 42 examples grouped by use case, the pros and cons, and how to write good ones.

Dichotomous question example: a yes/no survey question in Tapzy

What are dichotomous questions?

A dichotomous question is a closed-ended survey question with exactly two answer options, such as Yes/No, True/False or Agree/Disagree. The two options are opposites, so each respondent must pick one. Researchers use them to collect clear, fact-based answers that are fast to give and easy to analyze.

The word “dichotomous” comes from the Greek dichotomia, meaning “a cutting in two.” A dichotomy splits something into two separate parts, and that is exactly what these questions do with your audience. You will also see them called binary questions or yes or no survey questions.

Types of dichotomous questions

The answer pair changes the meaning. Here are the six most common types.

Six types of dichotomous questions: yes/no, true/false, agree/disagree, fair/unfair, like/dislike and have/haven't

Yes / No

The most common type. Use it for facts, behavior and eligibility.

  • Do you currently own a car?
  • Did you receive your order on time?

True / False

Best for knowledge checks, quizzes and policy acknowledgments.

  • The Earth orbits the Sun once every 365.25 days.
  • Employees must complete safety training every year.

Agree / Disagree

Captures a simple position on a statement. (A Likert scale adds levels in between.)

  • The checkout process was easy to follow.
  • Remote work should be an option for all staff.

Fair / Unfair

Useful for questions about pricing, policies and decisions.

  • Do you think our new subscription price is fair or unfair?
  • Was the performance review process fair or unfair?

Like / Dislike

Quick reactions to a design, feature or piece of content.

  • Do you like or dislike the new homepage design?
  • Did you like or dislike this episode?

Have / Haven't

Good for past experience and screening.

  • Have you or haven't you attended one of our webinars?
  • Have you or haven't you traveled abroad in the past 12 months?

When to use dichotomous questions

Dichotomous survey questions work best when the real answer has only two sides. Use them for:

  • Screening and qualifying respondents. Remove people who do not fit your target group before they answer the full survey (for example, “Are you 18 or older?”).
  • Branching with conditional logic. A “Yes” can open a follow-up section, while a “No” skips it.
  • Quick polls. One question, one tap. Great for websites, emails and live events.
  • Eligibility checks. Grants, offers, appointments and signups often depend on simple yes/no conditions.
  • Fact-based answers. Things like “Did you receive the email?” have a clear right answer.

If the honest answer is “it depends” or “somewhat,” choose a different question type.

Pros and cons of dichotomous questions

ProsCons
Quick to answer: one tap, little thinking needed.No nuance: no room for “a little” or “sometimes.”
Easy to analyze: results show as simple percentages.Forced choice: people in the middle must pick a side.
Higher completion: short, easy questions reduce effort and drop-off.Possible bias: wording and answer order can push people toward one answer.
Good for logic branching: two clean paths make skip logic simple.No “why”: you learn what people think, not the reason behind it.

The fix for most cons is simple: pair your dichotomous questions with an open-ended follow-up where the reason matters.

Dichotomous vs other question types

Question typeWhat it isBest useExample
DichotomousTwo opposite answer optionsScreening, facts, branching“Have you used our app before?” Yes / No
Multiple choiceThree or more fixed optionsPreferences, categories“Which plan are you on?” Free / Pro / Team
Likert scaleLevels of agreement, usually 5 or 7 pointsAttitudes and opinions“The app is easy to use.” Strongly disagree → Strongly agree
Rating scaleA score on a numeric or star scaleSatisfaction, quality“Rate your support experience from 1 to 5.”
Open-endedFree-text answerReasons, ideas, stories“What could we improve?”

All of these except open-ended are closed-ended questions. Dichotomous questions are simply the most restricted kind of closed-ended question.

Best practices for writing dichotomous questions

1. Make the options mutually exclusive

Each person should fit only one answer. If both answers could be true, rewrite the question.

2. Avoid leading wording

Avoid

“Don’t you agree our new design is much better?”

Better

“Do you prefer the new design to the old one?”

Pew Research Center's guide to writing survey questions explains how wording and question order can change results.

3. Ask one thing per question

Avoid

“Was our staff friendly and fast?”

Better

“Was our staff friendly?” then “Was our service fast?”

This is called a double-barreled question. A “No” to the first version could mean unfriendly, slow or both, so you cannot act on it.

4. Add “Not sure” only when you need it

A third option like “Not sure” or “Prefer not to say” makes the question no longer strictly dichotomous. That is fine when people truly may not know. Leave it out for clear facts, or many people will take the easy way out.

5. Follow up with an open-ended “why”

Avoid

“Would you recommend us?” and the survey ends.

Better

“Would you recommend us?” → if No: “What is the main reason?”

One extra text box turns a number into something you can act on.

6. Use them for skip logic

Place them at the start of a section and send people only to the questions that apply to them.

7. Keep the answer order neutral

Use the same order across the survey (for example, always Yes then No). For opinion pairs like Agree/Disagree, keep the positive and negative answers in a consistent position so nobody is nudged toward one side.

Step 5: Analyze results

Open Answers. Each Yes/No question becomes a chart, so you can see the split at a glance.

Dichotomous questions are short, clear and easy to analyze. They are ideal for screening people, checking facts and powering conditional logic. Their main weakness, the lack of nuance, is easy to fix: write neutral wording, ask one thing at a time and add an open-ended “why” where it matters. Use the 42 examples above as a starting point, then create your first yes/no survey in Tapzy.

Frequently asked questions

What is a dichotomous question in research?

In research, a dichotomous question is a closed-ended question with only two possible answers, such as Yes/No or True/False. Researchers use it to measure facts, behavior or eligibility. Because the data is binary, it is easy to count, compare between groups and use in statistical tests that need two categories.

Is a yes/no question dichotomous?

Yes. A yes/no question is the most common type of dichotomous question because it offers exactly two opposite answers. If you add a third option such as "Not sure" or "Maybe," it is no longer strictly dichotomous. It then becomes a short multiple choice question instead.

What is an example of a dichotomous question?

A classic example is "Are you 18 years of age or older?" with the answers Yes and No. Others include "Did you receive your order on time?" (Yes/No), "The checkout was easy to use" (Agree/Disagree) and "Water boils at 100°C at sea level" (True/False).

What is the difference between dichotomous and multiple choice questions?

A dichotomous question has exactly two answer options that are opposites. A multiple choice question has three or more options, and they do not have to be opposites. In fact, dichotomous questions are a special, two-option kind of multiple choice question. Use them for clear facts and multiple choice for preferences.

What are dichotomous key questions?

A dichotomous key is a biology tool for identifying living things. It asks a series of paired choices, such as "Does it have feathers? Yes / No," and each answer leads to the next pair until one organism remains. Surveys with conditional logic work the same way: each two-way answer decides the next question.
