What is the role of "Quotas" in a Qualtrics survey?

Quotas in a Qualtrics survey play a critical role in controlling the distribution of responses based on specific demographic characteristics. By setting quotas, researchers can ensure that their survey sample includes a balanced representation of various demographic groups, such as age, gender, ethnicity, or any other relevant criteria. This is particularly important in studies where the research aim is to understand differences in perspectives or behaviors across these groups.

Using quotas helps prevent biases that can arise from over-representing or under-representing certain demographics, thus enhancing the validity of the survey results. When the predetermined number of responses from a particular demographic group is reached, the survey can automatically stop collecting further responses from that group, allowing for a more structured and controlled data collection process.

Other functions, such as setting time limits for completion, randomizing response patterns, or analyzing open-ended questions, do not pertain to the function of quotas. Quotas are specifically designed to manage participant demographics, making option B the correct choice.
