G&R Block

What is G&R?

Grouping & Randomization lets you:

Group blocks to target specific respondent segments.
Randomize block or group execution to remove order bias.
Set quotas to control how many respondents see each group or block.

When to Use It?

Use G&R when you want to:

Test different versions (e.g., product concepts, messages) across audience segments
Avoid bias by shuffling block order
Control respondent distribution across groups or paths

How to Set Up G&R Block

1. Add G&R Block - Click “Add G&R Block” from the available blocks.

2. Create Groups - By default, one group is added automatically when you insert a G&R block. You can rename it and add up to 10 groups in total.

3. Add Blocks to Each Group - Drag existing blocks or create new ones inside each group (can add up to 5 blocks per group).

4. Edit Group Name (Optional) - Click the group name to rename it - e.g., “Frequent Buyers” or “Concept A”.
