RESEARCH DESIGN AND METHODOLOGY
In general, a research design is like a blueprint for the research.
Research Methodology concerns how the design is implemented and the
research is carried out.

AJ CROSS-SECTIONAL DESIGN
A cross-sectional design is used for research that collects data on relevant variables
one time only from a variety of people, subjects, or phenomena.
A crosS-sectional design provides a snapshot of the variables included in the study,
at one particular point in time.
Cross-sectional designs generally use survey techniques to gather data, for example,
the U.S. Census.

AJ CROSS-SECTIONAL DESIGN
• Advantages:
data on many variables,
data from a large number of subjects,
generate hypotheses for future research,
data useful to many different researchers.
Disadvantages:
increased chances of error,
increased cost with more subjects and each location,
cannot measure change,
cannot establish cause and effect
