Dr. Redbull conducts a study to determine whether her new energy drink helps children perform better on spelling tests. She randomly assigns children to one of two groups: Group 1 receives her energy drink and Group 2 receives water. She then gives both groups a spelling test and compares the results. Which of the following is true about this study?
A. Group 1 is the independent variable and Group 2 is independent variable.
B. The independent variable is the type of drink the children recieve.
C. Group 2 is the experimental group.
D. This is the corelational study.

The correct option is C. Group 2 is the experimental group. You alter an independent variable and track its impact on a dependent variable in an experimental design.

What is an Experimental design?

The technique of doing research in a methodical, controlled manner—known as the experimental design—ensures that accuracy is maximized and that particular inferences about a hypothesis statement can be made.

Thus, The test group is group 2, therefore. In an experimental design, you change one independent variable while monitoring the effect on the other. A factor's or independent variable's impact on a dependent variable has to be determined.
