Outlines
📊 Strengths of Quantitative Research
The first paragraph discusses the strengths of quantitative research, emphasizing that its advantages are context-dependent rather than an absolute measure of superiority over qualitative research. It highlights four main strengths: objectivity and accuracy due to the use of numerical data and statistical analysis, which minimizes bias; the ability to develop universal laws based on an objectivist epistemology; the capacity to handle large sample sizes for broader generalizations; and efficiency in data gathering through standardized instruments and potential automation. It also touches on cost efficiency as a result of these efficiencies.
🔍 Weaknesses of Quantitative Research
The second paragraph explores the weaknesses inherent in quantitative research. It points out that while quantitative methods are efficient, they may lack detailed insights into the participants' thoughts and behaviors due to a focus on numerical responses. The paragraph also notes that an overemphasis on objectivity can lead to an oversight of the underlying meanings of phenomena, which cannot always be captured by statistics. Additionally, the artificiality of controlled environments in quantitative research may not reflect real-world scenarios. The potential for improper representation of the target population and the limitation of preset answers in questionnaires are also discussed as weaknesses. Lastly, the paragraph mentions the complexity and difficulty of statistical analysis required for quantitative research, which can be a barrier for researchers without a statistical background.

Transcripts
strengths and weaknesses of quantitative
research
at the outset it must be noted that when
we talk about the strengths of
quantitative research we do not
necessarily mean that it is better than
qualitative research nor we say that it
is inferior to qualitative research if
we talk about its weaknesses
hence these strengths and weaknesses
depend only on a specific purpose they
serve such as in terms of the problems
or gaps that it aims to address or in
terms of the time needed to complete the
research
this means therefore that quantitative
research is better than qualitative
research only in some respects and vice
versa
so what are some of the major strengths
of quantitative research
first in terms of objectivity and
accuracy
if the issue is about objectivity and
accuracy then quantitative research is
strong and more preferable because
as we may already know quantitative
research explains phenomena according to
numerical data which are analyzed by
means of mathematically based methods
especially statistics
in this way biases are reduced to the
minimum and analysis and interpretations
are more objective and accurate
in fact another important point to
remember in quantitative research is
that it is informed by objectivist
epistemology
this means that quantitative research
seeks to develop explanatory universal
laws for example in social behaviors by
statistically measuring what it assumes
to be a static reality
in relative vein a quantitative approach
endorses the view that psychological and
social phenomena have an objective
reality that is independent of the
subject that is the knower or the
researcher and the known or subjects are
viewed as relatively separate and
independent
hence in quantitative research
reality should be studied objectively by
the researchers who should put a
distance between themselves and what is
being studied
in other words in quantitative research
the researcher lets the object speaks
for itself by objectively describing
rather than giving opinions about it
this explains why quantitative
researchers are supposed to play a
neutral role in the research process
hence the meaning participants ascribed
to the phenomenon studded is largely
ignored in quantitative studies
second in terms of sample size
it must be noted that a broader study
can be made with quantitative approach
which involves more subjects and
enabling more generalizations of results
in fact scholars and researchers argue
that one major advantage of quantitative
research
is that it allows researchers to measure
the responses of a large number of
participants to a limited set of
questions
also quantitative methods and procedures
allow the researchers to obtain a broad
and generalizable set of findings from
huge sample size and present them
succinctly and parsimoniously
third in terms of efficiency in data
gathering
in terms of data gathering quantitative
research allows researchers to use a
pre-constructed standardized instrument
or predetermined response categories
into which the participants varying
perspectives and experiences
are expected to fit
hence data gathering in quantitative
research is faster and easier
in fact data gathering in quantitative
research can be automated via digital or
mobile surveys which
for example
allows thousands of interviews to take
place at the same time across multiple
countries
as we can see data gathering in
quantitative research is efficient and
requires less effort
and fourth in terms of cost efficiency
since data gathering in quantitative
research is efficient and requires less
effort then obviously the cost of
someone conducting quantitative research
is typically far less than in
qualitative research
so much for the major strengths of
quantitative research
let me now discuss very briefly its
major weaknesses
first is that results in quantitative
research are less detailed
since results are based on numerical
responses then there is a big
possibility that most results will not
offer much insight into thoughts and
behaviors of the respondents or
participants
in this way too results may lack proper
context
second because quantitative research
puts too much emphasis on objectivity
and accuracy it does not consider
meaning behind phenomena
needless to say in every phenomenon
there are always important points that
cannot be fully captured by statistics
or mathematical measurements
indeed not all phenomena can be
explained by numbers alone
third is on the issue of artificiality
quantitative research can be carried out
in an unnatural environment so that
controls can be applied
this means that results in quantitative
research may differ from real-world
findings
fourth is that in quantitative research
there is a possibility of an improper
representation of the target population
improper representation of the target
population might hinder the researcher
from achieving its desired aims and
objectives
despite the application of an
appropriate sampling plan still
representation of the subjects is
dependent on the probability
distribution of observed data
as we can see this may lead to
miscalculation of probability
distribution and falsity in proposition
fifth quantitative research is limiting
quantitative research employs preset
answers which might ask how people
really behave or think urging them to
select an answer that may not reflect
their true feelings
also quantitative research method
involves structured questionnaire with
close-ended questions which leads to
limited outcomes outlined in the
research proposal
in this way the results expressed in a
generalized form cannot always represent
the actual occurrence or phenomenon
and sixth is the difficulty in data
analysis
quantitative studies require extensive
statistical analysis
which can be difficult to perform for
researchers from non-statistical
backgrounds
statistical analysis is based on
scientific discipline and hence
difficult for non-mathematicians to
perform also quantitative research is a
lot more complex for social sciences
education sociology and psychology
effective response should depend on the
research problem rather than just a
simple yes or no response
for example to understand the level of
motivation perceived by grade 12
students from the teaching approach
taken by their class teachers mere yes
and no might lead to ambiguity in data
collection and hence improper results
instead a detailed interview or focus
group technique might develop in-depth
views and perspectives of both the
teachers and children
