For researchers planning a clinical, laboratory, or field experiment, get help choosing a random assignment method that fits your study. Compare simple, blocked, and stratified randomization, then map out assignment steps and allocation concealment. Share group counts or baseline measurements to check for imbalances and consider what they mean for your analysis. Leave with an assignment plan, a reproducible method, and a balance-check checklist.

What it writes
- Random assignment procedure
- Block and stratum plan
- Baseline balance-check checklist
How to use it
In your first message, include the number of study arms, expected enrollment, enrollment pattern, and variables that must be balanced; these determine whether simple, blocked, or stratified assignment fits.
What you bring
- Number of participants and study arms
- Important baseline variables or site groups
- Enrollment timing and assignment constraints
- Define eligibility and treatment groups
A good fit for
- Planning treatment and control assignments for a small clinical study
- Balancing study arms when participant enrollment happens in batches
- Checking baseline imbalances after random assignment is complete
Ways to start
A few requests this Agent can handle.
I’m assigning 48 participants to two treatment arms over six months. Explain whether blocked randomization fits and give me an allocation plan.
Our trial has 80 participants and two sites. I want balanced treatment groups by site and age band; compare stratified and blocked randomization.
Here are baseline ages and group assignments for 30 participants: treatment ages 22, 24, 31; control ages 23, 29, 35. How should I check balance and report it?
