Pocock-Simon Minimization

Balanced form allocation,
made effortless.

Enter the project code you received from your researcher to get started.

The project code looks like: abc-123 — provided by your study organizer.

How does it work?

Three simple steps — from receiving a code to completing your form.

1

Receive your code

Your study organizer shares a unique project code with you via email, paper, or a link.

2

Answer a few questions

You'll be asked a short set of screening questions about yourself — no personal data is stored.

3

Get redirected

Guni's algorithm assigns you to the most appropriate form and redirects you there instantly.

The Science

What is the Pocock-Simon algorithm?

The Pocock-Simon minimization method is a gold-standard adaptive randomization technique widely used in clinical and academic research. Unlike simple randomization, it dynamically assigns each new participant to the group where they create the least imbalance across key stratification variables.

This ensures that your study groups remain comparable at all times — even with a small number of participants — leading to more statistically valid results.

  • Real-time balance across multiple covariates
  • Reduces selection bias without sacrificing randomness
  • Widely used in clinical trials and academic studies
  • Tie-breaking via controlled randomization

Built for researchers

Everything you need to run a properly randomized study — with zero coding required.

Multiple forms

Create any number of study variants. Guni distributes participants across all of them intelligently.

Live distribution tracking

Monitor participant allocation across groups in real-time from your admin dashboard.

Secure & private

No personal participant data is stored. Admin access is protected via Google or Microsoft SSO.

Auto-close projects

Set end dates or participant caps. Projects close automatically when targets are reached.

Prefilled form links

Participants are redirected to pre-filled Microsoft Forms links — no re-entering answers.

Multi-project management

Run multiple studies simultaneously, each with their own questions, forms, and settings.
