Introduction:

The placebo can be defined as the substance, which do not have a specific inherent value or medicinal value. In an experiment the placebo is provided to the control group and the experimental group to maintain a general condition for both.

Expert Solution & Answer

Explanation of Solution

During any experiment, the placebo is used as a substance, which have 0 value of the experimental variable. The placebo helps in maintaining the similar condition for the experimental and the control group. This way, the placebo allows to minimize the effect of other variables, such as temperature, pressure, etc.

Conclusion

The placebo allows treatment of the control group similar to the experimental group except for the independent variable being tested in the experimental group. Hence, it reduces the effect of other variables, which are not required to be tested.
