A controlled experiment is an experiment that includes at least two groups, one of which does not receive the experimental treatment (Option b).

  • An experiment is a procedure used to test (either confirm or reject) a working hypothesis.

  • In an experiment, an experimental group is a collection of subjects that receives the same treatment.

  • A control group is a group that is used to make comparisons in an experiment.

  • This group (control group) consists of participants/subjects that do not receive the treatment, allowing to make comparisons with other experimental groups.

In conclusion, a controlled experiment is an experiment that includes at least two groups, one of which does not receive the experimental treatment (Option b is correct).
