Text-Answer questions allow you to enter more than one correct answer so you may add variations on the correct answer in case your participants enter a misspelling, a variation/rephrasing of the correct answer, etc.
For example, if your trivia question asks, "Where does the President of the United States of America live?" The answer could technically be many phrases. Such as The White House or White House or 1600 Pennsylvania Ave or 1600 Penn Ave, etc. Crowdpurr allows you to enter up to 10 correct-answer variations in order to try to capture as many correct responses as possible from your participants.
Set the Correct Answer(s) of a Text or Numerical Question
To set the correct answer for a question, click on the answer you want to edit under Correct Answer(s). You can click the answer itself, or the green Edit (pencil) button. This puts the answer into Edit mode. The Correct Answer input will now allow you to type in a correct answer. Simply type in the correct answer, then click the green Save (checkmark) button to save the answer. As answers are received from your crowd, Crowdpurr will mark them with the Correct badge if they match any answer in the Correct Answer(s) area.
Add Additional Correct Answers
Since Text-Answer and Numerical-Answer questions allow you to have multiple correct answers, this can help with the aforementioned responses that don't exactly match a single correct answer value by adding in multiple variations of the correct answer to match more common responses.
Simply click the Add Another button, type in your additional answer, and click the green Save (checkmark) button to save the answer.
You may add up to 10 correct answer variations in order to match as many variations as possible.
