This article tells you how to use the Participants table to:

The Participants table displays useful information about every participant who started your tree test, and can be used to clean and filter your tree test data.

It’s a good idea to take some time to review the table before you start your analysis. This will give you a better understanding of which participants you want to include in your results.

Participants who complete all tasks are automatically placed in the ‘included in results’ table, while those who don’t complete all tasks (or are rejected by our recruitment panel), are placed in the ‘excluded from results’ table. It's a good idea to look over the included participants to make sure they meet your needs.

For example, you could sort the table by time taken, and exclude participants who you consider were too quick or took too long. If someone completes 8 tasks in only 30 seconds, you can be quite sure they haven't completed your study as seriously as you want.

Participants are considered to have 'abandoned' a study if they don't complete any tasks and if they don't reach the final page (your Thank You page or redirect URL). These participants are automatically excluded from your results.

We still include them in your Participants table so that you can choose to include them if you want to. For example, you might see that a participant marked as 'abandoned' has completed 60% of tasks, which will still give you valid data as Treejack tasks are scored individually.

An effective approach to analyzing your card sorting results might involve looking at the results of different demographics separately.

To segment and reload your results based on participant identifiers or URL tokens, look in the table for the identifier or token, and select them all using the check box. You can filter your results by clicking ‘Filter to selected participants’. The filter will now be applied across your results.

If your participants completed screening, pre-study or post-study questions that have pre-set answers (like multi-choice), you can segment your results based on their answers. Press the ‘Add filter’ button at the top of the page and select ‘Question response’, then choose the question and response you want to filter to. Press ‘Apply filter’ to reload the results to your new criteria.

Tip: If you used our in-app recruitment tool, you can easily replace study participants should you need to. Read more about replacing participants in-app and our participant response flagging feature here.
