Describe and differentiate the three methods to control extraneous variables
What will be an ideal response?
Extraneous variables can be controlled by holding them constant, or by matching them across treatment conditions, or by randomizing them across treatment conditions. If a variable is held constant, then it is the same for all treatment conditions and cannot be responsible for differences between treatments. Similarly, if a variable is matched across treatments, then it is the same for all treatment conditions and cannot be responsible for differences between treatments. Finally, if a variable is randomized across treatments, then it should not change systematically from one treatment to another, and it should not be responsible for differences between treatments.
