Answer:
This question is incomplete; the complete part is asking whether the statement about the independent variable is; True/False
The correct answer is False
Explanation:
In an experiment, the independent variable is the variable that the experimenter controls or manipulates in order to effect a change or bring about a response. The variable that responds to this manipulation is the dependent variable.
In this experiment involving Brittany, who is investigating how fast Brian will react to three different sounds, the independent variable is the DIFFERENT SOUNDS because that's the variable that Brittany changes in order to effect a response I.e. how fast Brian will react. Hence, the time it takes brian to react is rather the dependent variable.
