To understand the block randomizer you have to know what a survey block is. A survey block is a group of questions within the survey. Survey blocks simplify the way questions are ordered and presented to survey takers. They enable the survey creator to display a set of questions randomly.
The block randomizer helps to present the survey blocks in random order when a respondent reaches a specified section of the survey. This is useful when you need to randomly show a question from a group of questions or randomly show different sections of a survey to gather a variety of responses.
This help file will show you how to add, merge, and split blocks, as well as how to randomize questions within a block, and reorder blocks within the survey.
Setting up survey blocks
Without any survey questions, you will see the survey template blocks where you can add or merge them together.
Create a survey block:
Create a new survey. A survey block will be created automatically in the new survey. All questions will be added to this default block.
To create a new block, click on ‘Add Block’.
Preview a survey block:
Click on the three dots to the right of the survey block. Click on ‘Preview.’
With this option, you can preview all questions in a specific block.
Reorder a survey block:
To reorder blocks within the survey, click on the three dots and select ‘Reorder.’
Drag and drop blocks in preferred order and click on ‘Reorder Blocks’.
Display questions randomly in a survey using a block
To display questions randomly to different respondents, access the three dots to the right of the survey block and select ‘Question Randomization’.
Select questions under the current display order. Use the top/down arrows or left/right arrows to change the order of the questions.
Select the block, access the block settings and click on ‘Delete’.
Split a survey block into two:
You can split one block of survey questions in two.
To split the block, click on ‘Split Block at the bottom of the question from where you want to create a new block. It will divide the existing block into two blocks.
Splitting a block will reset the question randomization within the block.
Merge two or more survey blocks
Merging two survey blocks will combine all the questions in those blocks.
Merging two blocks will reset the question randomization within both the blocks.
Rename a survey block
Click on the block’s name and edit it. To expand and collapse survey blocks, click on the top-left icon.
Go to your survey. Click on ‘Tools’.
Click on ‘Block Randomizer’ from the drop-down menu.
Click on ‘Add Randomizer’ to add a section for the randomizer.
Drag and drop the blocks in the section and select the number of blocks you want to randomly display to the respondents.
Click on save.
The order decided under block randomizer will be the default order of your survey.
Reset block randomizer:
To reset the survey block randomizer, delete the randomizers added for that survey.
Go to the survey and click on the Tools button.
Click on ‘Block Randomizer’.
Click on ‘Delete ‘ on the top-right position of the randomizer.
Can I see which blocks were displayed and in which order for each respondent?
