In order to summarize the responses, you need responses. If you already have a Google Form go open up the spreadsheet that contains the data. If you did not connect your Google Form to a spreadsheet you can view the summary of responses from the Form’s edit screen.

Form Menu

In the Google spreadsheet there is a menu option “Form” to the left of the “Help” menu. Under this menu option is the choice to “Show Summary of Responses”
