Research Methods for Communication Sciences Test Questions with Detailed Answers Latest Update
2014-2025 (Already Passed)
Key functions of concepts - Answers - Communication
- Perspective
- Classification and Generalization
- Component of Theory
Conceptual Definitions - Answers Describe concepts using other concepts
Concepts are abstract and don't exist in the real world
-> Bridge the gap between theoretical concepts and observable phenomena
Operational Definitions - Answers Describe a set of procedures a researcher can follow to establish the
existence of the phenomena described by a concept
Quantitative research - Answers abstracting information to generalize findings beyond specific instances
-> Understanding the subjective meanings and explore in-depth perspectives
Qualitative research - Answers Works with numerical data aiming for objective patterns
Research problem - Answers Question or issue that requires a response in the form of a structured
scientific inquiry
Units of analysis - Answers what will be studied and what must be defined -> focal point of research
Dependent variable (Y) - Answers The variable the researcher is trying to explain
Independent variable (X) - Answers The variable that causes a change in the dependent variable
Control variable - Answers The variable used to test the possibility that the relation between the
dependent and independent variables is spurious
Continuous variable - Answers Can take away any value within a given range and can be measured with
great precision (e.g., 10 inches or 10,5 inches)
Discrete variable - Answers Can only take distinct, separate values and often represents counts or
categories (e.g. no values like 3.5 children)
, Relation - Answers Positive or Negative
a connection between two or more variables
If relation between X and Y = covariation
Covariation - Answers X and Y change together in a systematic manner: when one variable changes, the
other variable also changes in a predictable way
Magnitude - Answers Perfect relation: changes in Y are precisely determined by changes in X
Zero relation: no systematic connection
Hypotheses - Answers Hypotheses must be clear (conceptually & operationally)
Hypotheses are specific (expected relations among variables)
Hypotheses are testable with available methods
Scientific hypotheses are value-free
H0, H1 - Answers H0 = there is no significant difference or relationship between the variables being
studied
H1 = there is a significant difference or relationship between the variables being studied.
Classical experimental research design - Answers Experimental group exposed to the independent
variable (treatment)
Control group (not exposed)
