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.
If an experiment was comparing the effects of different fertilizers on plant growth, the plants that received no fertilizer are the control group. The other groups of plants that were treated with different kinds of fertilizer have their growth compared to that of the control growth to determine what fertilizers are effective.Learn More
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.Full Answer >
Experimental controls are mechanisms in science that eliminate extraneous factors that might otherwise affect the results of an experiment. By creating a second set that is unaffected by the phenomenon being measured, scientists are able to isolate the phenomenon by contrasting the test group with the control group.Full Answer >
A control in an experiment typically refers to the control group, which is the group that is not being exposed to the element or factor being tested. The other group is the experiment group. The only difference between the two groups should be the experiment factor.Full Answer >
The control group in an experiment does not receive a treatment or experimental condition. Researchers compare results from the experimental group with those of the control group to find an effect or statistically significant difference with the treatment.Full Answer >
