The document outlines the distinctions between inquiry and research, emphasizing that inquiry is a preliminary stage of investigation while research is a structured process aimed at generating new knowledge. It describes the characteristics, strengths, and weaknesses of quantitative research, highlighting its objective nature and reliance on numerical data for analysis. Additionally, the document discusses the importance of quantitative research across various fields, such as social sciences, natural sciences, and business.

3. INQUIRY VS RESEARCH

4. INQUIRY VS RESEARCH
INQUIRY RESEARCH
DEFINITION
refers to the process of asking
questions to gain information,
clarify doubts, or explore a topic.
It is often the initial stage of
investigation where curiosity
leads to questioning.
is a systematic and methodical
process of investigating a specific
question, problem, or hypothesis.
It involves collecting, analyzing,
and interpreting data to draw
conclusions.
PURPOSE
is to gather basic information or
understanding. It can be informal
and may not necessarily follow a
structured method.
is to generate new knowledge,
validate theories, or solve specific
problems. Research is usually
more formal and structured,
often leading to documented
findings or publications.

5. INQUIRY VS RESEARCH
INQUIRY RESEARCH
SCOPE
is broader and less structured,
often involving open-ended
questions. It can be done on a
personal level, in everyday
situations, or as a preliminary
step in a larger investigation.
more focused and structured,
often following a specific
methodology. It typically involves
a clear objective, detailed
planning, and rigorous analysis.
EXAMPLES
Asking questions in a classroom
to understand a concept, seeking
information from a professional,
or exploring a new topic out of
curiosity.
Conducting experiments in a
laboratory, writing an academic
paper, or performing a market
analysis for a business.

6. RESEARCH
ETYMOLOGY: “research” was coined from French word
“cerhier” which means “seek” . The prefix “re”
means to repeat.
 Research is to repeat looking or seeking for something.
 A natural day-to-day activity of gathering information.
QUALITATIVE RESEARCH
seeks to answer questions about why and how people behave in
the way that they do. It provides in-depth information about
human behaviour.
QUANTITATIVE RESEARCH
is “explaining phenomena by collecting numerical data that are
analysed using mathematically based methods (in particular
statistics).”

11. QUANTITATIVE RESEARCH
• an objective, systematic empirical investigation of
observable phenomena through the use of
computational techniques.
• concerned with numbers and its relationship with
events .
• suggests that the data concerned can be analyzed
in terms of numbers .

21. STRENGTHS AND WEAKNESSES OF
QUANTITATIVE RESEARCH

22. STRENGTHS:
1.It is objective.
2.Uses statistical techniques.
3.Quick and easy analysis of data.
4.Quantitative research design is
the most reliable and valid way of
concluding results.
5.Quantitative studies are
replicable.

23. WEAKNESSES:
1.It requires a large number of
respondents.
2.It is costly.
3.The information and contextual factors
to help interpret the results or to explain
variations are usually ignored.
4.Many information are difficult to gather
using structured research instruments.
5.If not done seriously and correctly, data
from questionnaires may be incomplete
and inaccurate.
