The Short Version

Randomly assign text, image, or video treatments and inspect treatment effects, confidence intervals, balance checks, and graphs free. A practical way to begin is to create the control condition first so it becomes the reference arm, then add one or more treatment conditions using text, an image, or an embedded video. Finish by making sure you inspect arm means, mean differences, confidence intervals, balance diagnostics, open-text effects, and the standard treatment-effect graph in Results. The full walkthrough below explains each part in order.

Is This Guide for You?

Academic, nonprofit, product, and marketing researchers who need randomized survey experiments without buying an enterprise survey platform first.

Follow These Steps

Work through these 6 steps at your own pace. The wording is intentionally practical, and you can return to the checklist at the end when you are ready to review your work.

Create the control condition first so it becomes the reference arm.
Add one or more treatment conditions using text, an image, or an embedded video.
Place the primary outcome after treatment exposure and keep its wording identical across arms.
Preview every treatment path and generate synthetic responses to confirm the result workflow.
Publish the study and collect responses within the account's 2,000-response Free allowance.
Inspect arm means, mean differences, confidence intervals, balance diagnostics, open-text effects, and the standard treatment-effect graph in Results.

What This Helps You Accomplish

Random assignment and analysis need to stay connected. The Free plan stores the assigned arm, outcome answers, timing, quality flags, and respondent path, then calculates the comparison in the same workspace. Paid is required for downloadable production files and panel completion automation, not for seeing whether the experiment worked.

A Quick Confidence Check

Common Questions

Can I use this guide if I am new to this?

Yes. Academic, nonprofit, product, and marketing researchers who need randomized survey experiments without buying an enterprise survey platform first. Follow the steps in order, start with a small test, and use the final checklist before you field or report anything important.

What is the simplest way to get started?

Begin by create the control condition first so it becomes the reference arm. Next, add one or more treatment conditions using text, an image, or an embedded video. You do not need to perfect every setting before running a small preview or pilot.

How do I know when I am ready?

Use the confidence check above. In particular: Control arm first. Primary outcome chosen before fielding. Every arm previewed. Common outcome wording. When the decision is consequential, keep your study documentation and ask a qualified colleague or methods reviewer to examine the design as well.
