What is the primary reason for including a control in the design of an experiment?
to ensure that the results obtained are due to a difference in only one variable
the wavelength increases from bottom to top
It generates seismic waves that spread out in all directions around Earth.
changes in response to the change the scientists makes to the independent variable
It is the variable in an experiment that is changed in order to test the hypothesis.
temperature of the air increases
The control group is matched with the experimental group except for the one experimental variable.
