This document outlines and defines several types of research according to different criteria. It describes action research as research aimed at solving a specific, limited problem. Evaluation research specifies all possible courses of action to determine advantages, while developmental research focuses on finding or improving existing instruments or processes. Quantitative research utilizes statistics to determine results and often examines comparisons and relationships, whereas non-quantitative research gathers descriptive rather than quantitative data. Historical research describes past events, descriptive research describes present conditions, and experimental research predicts future outcomes.

1. TYPE OF RESEARCH ACCORDING TO SCOPE
 Action Research – this type of research is done on
a very limited scope to solve a particular problem
which is not so big. It is almost problem-solving.

2. TYPE OF RESEARCH ACCORDING TO CHOICE OF ANSWERS TO
PROBLEMS
 Evaluation Research – all possible courses of
action are specified and identified and the
researcher tries to find the advantages.

3. TYPE OF RESEARCH ACCORDING TO CHOICE OF ANSWERS TO
PROBLEMS
 Developmental Research – the focus is on finding
or developing a more suitable instrument or
process than has been available.

4. TYPE OF RESEARCH ACCORDING TO STATISTICAL CONTENT
 Quantitative or Statistical Research – is one in
which inferential statistics are utilized to determine
the results of the study. This type of research usually
includes comparison studies, cause-and-effect
relationships, etc.

5. TYPE OF RESEARCH ACCORDING TO STATISTICAL CONTENT
 Non-Quantitative Research – this research in
which the quantity or statistics is practically nothing.
Descriptive data are gathered rather than
quantitative data.

6. TYPE OF RESEARCH ACCORDING TO TIME AND ELEMENT
 Historical Research describes what was.
 Descriptive Research describes what is.
 Experimental Research describes what will be.
