Elements to consider in the choice of Research Design

1. The total population from which to select the study samples
2. The method of selecting the samples or study respondents:
3. The alternative versions of independent variables under
study:
4. The criterion measures evaluating the effects of the
independent variables; and The statistical treatment of
data, using various tools.

Different Research Designs

A. Quantitative Research

Test hypothesis and makes predictions through measured
amounts and ultimately describes an event by using numerical
figures. Statistical analysis is therefore applied to interpret
the numbers obtained from the data. In this regard, objectivity
of results are guarantee.

Experimental Research

This particular design is an inquiry on cause-and-
effect relationships, and is conducted in a specialized
setting, such as the laboratory, experimental unit or
research center. The researcher controls and
manipulates the independent variable and randomly
assigns the subjects to different conditions or
situations.
The benefit gained in experimental studies is the
possibility of establishing causal relationships
between independent and dependent variables
In experimental studies, the researcher consciously
manipulates or controls situations related to the study,
thus interfering with nature. Observations are done
under controlled conditions or in a controlled
environment (Abdellah, 2000).
