PR REVIEWER Flashcards
- Systematic and scientific investigation of numerical data and their relationships. Demands only real or factual and not emotional or cognitive data.
Qualitative Research
Excellent way to finalize result proving or rejecting a hypothesis
It filters out external factors results are real and unbiased
Strengths
Human nature is a lot more complex than a simple yes/no question
There is usually some ambiguity that requires retesting and refinement of the research design
Experiments can be difficult and expensive
Weaknesses
Types of Quantitative Research
- attempts describe the current status of a selected variable. It provides information to the subject of the research
Descriptive
- Answers the extent of the relationship of 2 or more variables based on statistical data. The data relationship and distributions of the variable are studied only.
Correlational
- Attempts to establish a cause-effect relationship. It’s independent variable is not manipulated and uses naturally formed groups
Causal-Comparative
- identifies and imposes control over all other variables. Independent variable is manipulated and the subject is randomly assigned
Experimental
- A survey is intended to acquire information from people concerning the predominance, distribution, and interrelations of variables within an identified group.
Survey
Different Fields
- It provides observational research through and based on surveys or correlational studies
Medicine
- To understand particular communication phenomena might be generalized to larger population
Communication
- To determine how human behavior relates with other people, individual differences that may affect human reactions
Behavioral
- to create educational principle based on understanding human behavior
Educational Psychology
- are properties or characteristics of some event, object, orperson that can be assigned with different values or amounts. In conducting quantitative research, especially in experiments, these variables are often manipulated.
Variables
Kinds of Variables
Independent Variable -
Dependent variable -
causes change in dependent variable. Manipulated by the researcher. It is hypothesized to affect the dependent variable. An independent variable is what the researcher manipulates to see if it changes the dependent variables.
Independent Variable -
- changes are caused by the independent variable. Not manipulated by the researcher but dependent on the independent variable
Dependent variable
- This links or intervenes between dependent and independent variables.
Intervening Variable
- This may increase/decrease the relationship between independent and dependent variable.
Antecedent Variable
