| Quiz:
Distinguishing independent
and dependent variables.
Read this tutorial on the
phases of research,
with a specific description of independent and dependent
variables.
Then, complete the self-quiz below:
Below are
examples of
research studies. Name the independent variable (IV) and the
dependent
variable (DV) for each one. Then check your results with the
answers.
A good tip for doing this exercise is to first name the 2 main
variables
in the study, then figure out which one influences the other. The
one doing the influencing is the IV; the one being influenced is the DV.
1. Study examining if t.v.
violence increases
