The 'control group' is an essential component of an experiment. This is because
1. A control group allows one to determine if a particular result is due to the experimental variable.
2. No, it's not essential in experimentation. A control group is not always necessary it depends on the experiment.
3. A control group allows for multiple variables to be tested at the same time.
4. A control group is required for the development of a prediction.
A controlled experiment is one that
proceeds slowly enough that a scientist can make careful records of the results.
tests experimental and control groups in parallel.
is repeated many times to make sure the results are accurate.
keeps all variables constant.
The purpose of the constant is to:
a. allow for adjustment of the control
b. eliminate other potential factors/variables in the experiment
c. allow for the dependent variable to show the necessary outcome
d. help prove the hypothesis correct
