Q:

What is the part of an experiment that is not being tested and is used for comparison?

A:

The control is the part of an experiment that does not change. The other parts of an experiment are constants, experimental group, independent variable and dependent variable.

Every experiment has five steps. These are make an observation, develop a hypothesis, design an experiment, conduct the experiment and analyze the results obtained, and make conclusions based upon the results obtained. The control is the part of the experiment that remains the same throughout and is what the experimental group is compared to during the experiment. The variables are what is changed and the results that are obtained based on those changes.

  • Q:

    Why is a control important in an experiment?

    A:

    The control is an important aspect of an experiment because it establishes the baseline that the experiment's subjects are compared to. Without a control, researchers would not have anything to compare the experiment's results to. Controls are also helpful because they permit scientists to identify possible mistakes or errors in the experiment if the control's results are not what they anticipated.
