TYPES OF QUANTITATIVE APPROACHES
Descriptive research seeks to describe the current status of an identified variable.
EXAMPLES
Description of tobacco use
Description of how time passes somewhere
These research projects are designed to provide systematic information about a phenomenon.
The researcher does not usually begin with an hypothesis, but is likely to develop one after collecting data.
The analysis and synthesis of the data provide the test of the hypothesis.
Systematic collection of information
Correlational research
Determine the extent of a relationship between two or more variables using statistical data.
In this type of design, relationships between and among a number of facts are sought and interpreted.
Recognize trends and patterns in data
Cause and effect
The data, relationships, and distributions of variables are studied only
EXAMPLES
The relationship between diet andanxiety
The relationship between intelligence and self-esteem
Causal-comparative
An independent variable is identified but not manipulated by the experimenter, and effects of the independent variable on the dependent variable are measured.
The researcher does not randomly assign groups and must use ones that are naturally formed or pre existing groups. Identified control groups exposed to the treatment variable are studied and compared to groups who are not.
EXAMPLES
The effect of magnet school participation on student attitude
The effect of age on lung capacity.
Experimental research
Uses the scientific method to establish the cause-effect relationship among a group of variables that make up a study
An independent variable is manipulated to determine the effects on the dependent variables.
Subjects are randomly assigned to experimental treatments rather than identified in naturally occurring groups.
EXAMPLES
The effect of a new virus treatment plan
The effect of a new cancer treatment plan
What is the basic methodology for a quantitative research design?
It uses deductive reasoning
the researcher forms an hypothesis
collects data in an investigation of the problem
uses the data from the investigation
After analysis is made and conclusions are shared, to prove the hypotheses not false or false.
