What is a sentence that uses control group?
In a scientific study, the control group is a set of subjects that does not receive the treatment being studied, used for comparison to evaluate the effectiveness of the treatment on the experimental group.
Why is it wrong for a researcher to assign the first subjects to show up for an experiment to the experimental group and the second group of subjects to arrive to the control group?
Assigning subjects based on arrival time can introduce bias into the study, as there could be systematic differences between subjects arriving early and those arriving late. This could confound the results of the experiment and make it difficult to determine the true effect of the treatment. It is essential to randomly assign subjects to experimental and control groups to ensure the groups are comparable at the start of the study.
Are subjects of psychological research.?
Subjects of psychological research are individuals who participate in studies or experiments to help researchers gather data and draw conclusions about human behavior, cognition, and emotions.

The findings from these studies can contribute to our understanding of human behavior and inform interventions and treatments.
