Experiments are used in statistical studies to compare the effect on the treatment group to the control group. For example, suppose a medical center wants to test if a new vaccine helps defeat breast cancer in women. To conduct a controlled experiment, researchers need to sample women with breast cancer and randomly assign them to groups.
Control Group | Treatment Group |
---|---|
Women with breast cancer that will not receive the vaccine. | Women with breast cancer that will receive the vaccine. |
Always be sure to consider the many advantages and disadvantages depending on the context and situation under study.
