How do I clear past survey results?
Open the RESULTS > INDIVIDUAL RESPONSES window. You will see all of the individual responses to your survey. The first column on the left has checkboxes that let you designate responses for BULK ACTION. Click on the checkbox in the header – this will select all of the responses on the screen. Scroll down to the bottom of the list, click on the SELECT A BULK ACTION button, and then select DELETE ALL RESPONSES.
This does not actually delete every response to the survey – just the ones that you have selected. You will have to repeat this operation again with a new list of responses, continuing until every response has been deleted.
