The General Tab provides an overview of response rates:

Completed =  The submit button was hit on the survey
Partial = The start/logon button has been hit, but the submit button has not been hit
Not Started = The start/logon button has not been hit

When on the General Tab, the horizontal bar display displays how many people completed the survey on each day the survey has been live.

For multilingual surveys, there will be a Language drop down that will allow you to toggle between the submissions filtered by the language in which the survey was taken.

Clicking on any one of the dates drills you down to the data for all the people that completed the survey on that date. In fact, anywhere in the Data Manager where you see something underlined, that’s a cue that there is a drill-down available.
