Students have asked these similar questions
A control group is_______ . a. a set of individuals that have a certain characteristic or receive a certain treatment b. the standard against which an experimental group is compared c. the experiment that gives conclusive results
A controlled experiment ________.
A.
includes one group for which the scientist controls all variables
B.
is repeated many times to ensure that the results are accurate
C.
includes at least two groups, one of which does not receive the experimental treatment
D.
includes at least two groups, one differing from the other by two or more variables
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.
