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
