which provides a baseline for an experimental investigation?\n○ hypothesis\n○ control group\n○ dependent variable\n○ independent variable
Answer
Answer:
B. control group
Brief Explanations:
In an experiment, the control group is not exposed to the independent - variable changes and serves as a baseline for comparison to see the effect of the independent variable on the dependent variable. A hypothesis is a proposed explanation, the dependent variable is what is measured, and the independent variable is what is manipulated.
