Closed questions have a particular set of answers for individuals to choose from. This is the opposite of an open-ended question in which an individual can say whatever they want as an answer. For the question "What is your favorite color?" to be a closed question the answers would be red, blue, green, yellow and orange with no options to list or choose another color. Open-ended the same question would have no choices and the individual could say anything they wished, like magenta or brown. Closed questions are frequently used when large amounts of participants and data are being used in order to easily quantify the responses.
