Study Planning Tool

Counterbalancing & Randomization Planner

Create reproducible participant schedules, inspect positional balance, and export an assignment plan before data collection begins.

Choose a design

Select the structure that matches how participants experience conditions.

Balanced Latin squareWithin-subject. Balances position and immediate carryover.RecommendedCyclic Latin squareWithin-subject. Balances position with fewer sequence constraints.Balanced assignmentBetween-subject. Assigns one condition using randomized blocks.

Define the study

Enter one condition per line and choose the planned sample size.

Conditions

Between 2 and 12 unique conditions.

Participants

Participant prefix

Randomization seed

Reuse the same seed to reproduce an identical plan.

Assignment plan

Balanced within-subject condition orders.

Participants: 24
Conditions: 4
Base sequences: 4
Balance: Complete cycles

Balance diagnostics

Position balanced

Each condition appears equally often in every position.
