The star rating poll is a generic 5-star rating scale. To create a rating poll follow these steps:
In the Polls section select the '+ Create new poll' button.
Enter the 'Title' of your poll or question.
Select Rating as the poll type.
That's all there is to it. The great thing about a 5-star rating scale is that it's so recognizable you don't need to specify what's high or what's low.
When the result is published not only do you see the number of votes for each star you also get the average response as well.
