Randomization of Questions

Randomize questions and blocks to balance exposure, reduce order bias, and boost reliability

Our customers told us they needed stronger control over order bias, especially in concept and ad testing. We listened.

Randomization was built for you: now you can vary question and block order to balance exposure, reduce bias, and keep your analysis clean and comparable.

What's new

Build Question Blocks to manage randomization in your projects.

  • Randomize within a block
    Shuffle the order of questions inside a block so each participant sees them in a different sequence, reducing order bias.
  • Randomize between blocks
    Shuffle the order of entire blocks, so different participants start with different themes, balancing perspectives across interviews.
  • Branching support
    Randomization works seamlessly with branching. Use randomization to minimize bias, and branching to skip irrelevant sections and create tailored flows.
  • Consistent analysis
    No matter the order, every response is rolled up correctly. Even if a question shows up as Q4 for one participant and Q7 for another, answers are aggregated together for clean, reliable analysis.

Randomization works in all supported languages and across both text and voice interviews.

Why It Matters

Randomization helps reduce order bias and enhances the validity of your results, aligning with industry best practices for designing surveys and interviews. It ensures each participant experiences a fair and balanced path, while keeping your outputs consistent and easy to compare. You can quickly implement this in your next project by enabling question block randomization to minimize bias without compromising on speed, logic, or clarity.
