Selection
Selection surveys break down into two main types- Single choice and Multiple choice. This does not refer to the number of answers you can create for the survey, but rather to the number of selections the user is allowed to make.
Single choice
Single choice works best when you have a question that you only want one definitive answer to. This can be anything from a user's favorite feature, to preferred method of contact, to an age range.
Multiple choice
Multiple choice works for questions where you would like a variety of feedback or a combination of answers. This can be things like reasons for choosing your product or requests for future features.
