Answer:
The independent variable would be the coffee.
Explanation:
In an experiment, the independent variable is something that is added or changed by the scientist in order to see if there will be a response.
In this case, the memory test score would be the dependent variable (something that changes as a result of a change in the independent variable).
Decaf coffee could be a control group, or a group that is treated the same as the independent variable but without being exposed in order to account for any outside factors.
Finally, the type of cup used would be a constant between the control group (using the decaf coffee) and the experimental group (the group with regular coffee).
Hope this helps!

Answer:
Independent variable
An
independent variable is a condition in a scientific study that is changed or
manipulated to test the effects on the dependent variable. The experimenter
controls the value of independent variable and its value represent inputs or
causes like potential reason for variation.
Additionally, there are
tendencies that independent variables are included in a scientific study especially
if the experimenter has no intention to test their effect directly.
