COMM 2030 Test 1 | 2026/2027 | Correct Answers | With
Complete Solutions
"Theories of international politics based on data from the Cold
War period aren't very useful for predicting international
relationships today." Correct Answers external validity is a
problem
Characteristics of scientific method Correct Answers Public,
objective, empirical, systematic, cumulative
Continuous Variables Correct Answers Can take on any value
and can be meaningfully broken into smaller subsections (i.e.
The amount of time playing violent video game,
Aggressiveness, Height / weight, Communication Competence,
Shyness)
Control Variables Correct Answers Boundary conditions that
affect the relationship between independent and dependent
variables. A variable whose influence a researcher wants to
eliminate, so that a research ensures study results are due to the
independent variable.
Control Variables Example Correct Answers On conversation,

tend to give hypotheses-confirming responses. (This happen
when the participants are volunteers)
Dependent Variables Correct Answers The variable of primary
interest and what a researcher is trying to explain
Dependent Variables Example Correct Answers Perceived
level of dissatisfaction with their own body images
Discovering theoretical explanations means Correct Answers
finding a theory
Discrete Variables Correct Answers Change by this step having
only a finite set of values (i.e. Gender, Religion, Nationality)
Evaluation Apprehension Correct Answers Research subjects
are afraid of being measured or tested. Participant's desire to
present a positive self-image to the researcher or at least to
provide no grounds for a negative one.
