Question 10

The control group can be measured against the experimental group as a standard of comparison.

In experimental design, the control group serves as a baseline to compare against the experimental group, allowing researchers to assess the effects of the independent variable.

A) Control

The control group is essential in experimental design as it does not receive the treatment or intervention that the experimental group does. This allows researchers to observe any changes and determine whether they are due to the treatment or other factors.

B) Responding

The responding group, often referred to as the dependent variable, is not a separate group but rather the outcomes measured in response to the experimental conditions. It cannot serve as a standard of comparison because it reflects the effects of the experimental manipulation rather than acting independently.

C) Manipulated

The manipulated group refers to the experimental group that receives the treatment or intervention. It is not a standard of comparison; instead, it is the group being tested to observe the effects of the independent variable.

D) Variable

The term variable refers to any factor that can change in an experiment, including independent and dependent variables. While important for understanding the experiment, variables themselves do not serve as a standard for comparison against the experimental group.

Conclusion

The control group is the only option that provides a valid comparison against the experimental group. It allows researchers to isolate the effects of the experimental treatment by comparing outcomes directly, while the other options either describe components of the experiment or refer to outcomes that do not serve as independent benchmarks.
