Add a Conditional Exclusion Constraint
Block certain variable combinations by setting up a conditional exclusion in the experiment UI.
Key Steps
Open the constraints panel — In your experiment, go to the constraints section.
Select conditional exclusion — Choose "Conditional Exclusion" as the constraint type.
Configure the condition — Define the IF condition: pick a variable and specify the range or categories that trigger the constraint.
Configure the exclusion — Define the THEN exclusion: pick a second variable and specify the values to block when the condition is met.
Save the constraint — Give it a descriptive name and save.
Good to Know
A conditional exclusion uses AND logic — all conditions must be met simultaneously for the exclusion to apply.
You can add multiple conditions to a single constraint for more complex relationships.
