experimental group takes the pre-test
before treatment while the other group
does not.

3. Factorial Design
➢ There is simultaneously manipulation of
two or more independent variables which
permit testing of multiple hypotheses in a
single experiment

4. Randomized Block Design

➢ In this design, there are two independent
variables, but one independent variable is
not experimentally manipulated due to the
heterogeneous randomized assignment of
subjects.
5. Crossover Design
➢ In this study, different people are randomly
assigned to different treatments. Subjects
are exposed to two different treatment or
conditions.

1. Non- experimental Research

The researcher does not interfere with nature, and the
conditions for research are realistic or natural.
This research is often known as "surveys", which
have less control over the study subjects and the setting
where it is conducted. They are research situations in
which the researcher cannot control and manipulate the
independent variable. They are mostly conducted in natural
settings such as schools, hospitals and other public health
agencies, and homes of patients, among others.

Types of Non-Experimental Design

a. Basic or Library Research
➢ This is intended to increase knowledge in
science. It is also called pure research for
purposes of generating new knowledge. Basic
research includes reading books and literature,
listening to discussions, journal analysis,
browsing articles from internet and website and
