Question

practice it! which of the following is a reason why having a control group is important in an experiment? a control group helps the scientist meet the minimum trial requirements for an experiment. a control group is needed if the scientist wants their experiment to be published in a scientific journal. a control group is only necessary when the scientist is comparing events that occur in different locations. a control group gives the scientist a set of data that shows what would have happened normally without interference so that the scientist can compare the data accurately.

Explanation:

A control group in an experiment is a baseline. It shows the normal outcome without any experimental manipulation. This allows scientists to compare results of the experimental group against it to accurately assess the effect of the variable being tested.

Answer:

A control group gives the scientist a set of data that shows what would have happened normally without interference so that the scientist can compare the data accurately.
