He said that “Research is what I am doing when I do not know what I am doing.”
Wernher Von Braun
seeks to solve and explain practical problems.
Applied research
systematic study that aims to gain knowledge or understanding of fundamental principles.
Basic research
The real aims of research are:
- create new knowledge or information
- utilize the new knowledge
- validate existing knowledge
- improve the research
(Research Design)
design to attempts to know the degree of relationship between two or more variables using statistical information
Correlational
(Research Design)
the most effective method of testing cause and effect relationships among variables
Experimental
(Research Design)
the simplest research design as in only tries to describe what exists and may
help uncover new findings and learnings
Descriptive
(Research Design)
tries to explain the cause-and-effect relationships among
variables
Causal-Comparative
also known as the input variable is the probable cause of an
occurrence. It does not easily change
Independent variable
also known as the outcome variable. It is affected by the
independent variables and changes due to the manipulation and alteration of the independent variable.
Dependent variable
(Categorical variable)
classifies individuals, objects, or responses based on the common characteristic though it is limited to descriptive categories
Ex: gender, religion, race, blood type
Nominal variables
(Categorical variable)
has a characteristic of nominal variables but ranked in a certain order
Ex: contest results, social status
Ordinal variables
(Numerical variable)
has the characteristics of the other three (3) variables. They are based on a fixed beginning point which is called a “true zero (0) point”, where the value of zero (0) does not exist
Ex: family income, voter registration for 2000, 2004, and 2008, number of
students per classroom, and others
Ratio variables
(Numerical variable)
that are rank ordered, with values in ranges
Ex: age, measurements like temperature
Interval variables
