In an experiment, half of the participants are randomly assigned to sleep on a new type of mattress, while the other half of the participants sleep on a standard mattress. The next night, the participants sleep on the other type of mattress. After the second night of sleep, the participants are asked which mattress made them feel more rested in the morning

Answer:

The difference in the responses of the participants is not likely due to confounding.

Explanation:

  • The treatment that the participants got during the experiment was clearly different with respect to each other as the types of mattresses offered were different.
  • Depending on the treatment, the outcome varied naturally as the difference in the treatment inevitably derived distinct responses from the participants. Hence, confounding did not have any role to play in the result of the experiment.
