good day

welcome to practical research 2 class i

am miss jenny vijay arimbuyutan

but you may call me miss a this video

lesson provides you assistance in

accomplishing the task in your learning

modules

today's session leads you through the

process of understanding concepts of

quantitative research

this leads you through the basic

elements of research which are essential

for good research practices

also this introduces the importance of

quantitative research in different

fields

at the end of this session you are

expected to

identify the different disciplines where

you can use quantitative research

emphasize the contribution of

quantitative research across

fields and illustrate the importance of

quantitative research across

fields

have you ever wondered how computing

networks determine the satisfaction

ratings

of their viewers per television show

aired in a specific time slot

numbers they truly project reality

have you also asked yourself where the

best spaghetti or fried chicken in town

is

you may ask your friends the most

mentioned brand or store wins in your

mind

and somehow gives you an idea what to

choose

numbers they represent meaning and

connect ideas

rankings and percentages are products of

quantitative research

most areas of study have to deal with

processes

that involve experimentations tests and

research

in these situations quantitative

measures are more or less involved

in validating results and findings

quantitative research

serves as a multi-purpose method for

example

to test to identify to count

to assess to clarify etc

some areas and the function of

quantitative research are provided in

this video lesson

so let's get started

number one education quantitative

research can be used in measuring the

level of performance of students

as well as teachers it can also be used

to assess the effectiveness of the

methods used the different programs

conducted

and the satisfaction of all stakeholders

and education sector

including students faculty parents

administrators the community the

government and non-governmental

organizations

through this research method the

interests of these groups can be

advanced or enhanced

by implementing quantifiable best

practices

number two business quantitative

research is a valued tool in business

when it is used intelligently it can

improve the overall marketing strategy

help the company make informed decisions

on how to move forward

with a particular product or service and

even solicit consumers opinions

for productivity this type of research

is largely utilized in product

development

to create favorable marketing campaigns

data that are often used in this type of

research are market size

demographics and user preferences

number three communication pieces are

often interested

in how an understanding of a particular

communication phenomenon

might be generalized to a larger

population

for example researchers can advance

questions like

what effect do disciplinary behavioral

control statements

have on a classroom or

what communicative behaviors are

associated with different stages in a

romantic relationship

number four demographics quantitative

research

samples of populations ideally are

collected by selecting respondents

randomly

from the larger populations you may use

quantitative research to discover

patterns

associations correlations and other

features of a population

researchers collect demographics to

inform readers about the sample of

respondents to their survey

the hope is this sample is the

representative of the larger population

number five economics you may use

quantitative research to evaluate

economic behavior and design economic

policies and techniques

applying quantitative methods models and

the corresponding procedures

help to make more accurate and efficient

research of complex

economic phenomena and issues as well as

their interdependence with the aim of

making the sessions

and forecasting future trends of

economic aspects and processes

number six sports medicine in this

discipline

a quantitative study may be done by

studying a phenomenon

like what the university of eastern

finland did

they investigated the relationship

between the growing of fast

food chains and obesity of children as

well as the intervention needed

to prevent the children's obesity from

reaching serious proportions

it had been found out that doing active

exercise would help the children have 26

to 30 percent less adipose tissue than

their peers who were physically inactive

number seven medical education

experimental research designs may

enhance the quality of medical education

the set design test intervention like

curriculum

teaching learning process or assessment

with an experimental group

either comparison or controlled group of

learners

may allow researchers to overcome

validity concerns

and infer potential cause and effect

generalizations

number eight behavioral science

relationship questions tend to explore

how one behavior

exhibited by people is related to other

types of behavior

examples are verbally aggressive

behaviors related to physical aggression

that is when a person has high level of

verbally aggressive behavior

does he or she tend to be physically

aggressive

certain supervisor communication skills

related to the emotional experiences of

employees

number nine psychology quantitative

psychologists

study and develop the methods and

techniques used to measure human

behavior and other characteristics

their work involves the statistical and

mathematical modeling of psychological

processes

the design of research studies and the

analysis of psychological data

number 10 political science many of the

phenomena that are studied in political

science can only be properly

investigated

using quantitative methods when

discussing political revolutions

and the emergence of political theory

quantitative data often describes the

circumstances

best

so those are the different fields or

disciplines where we can use

quantitative research

have you ever wondered on how would

quantitative research help you in your

chosen field

comment your answers below that's all

for today

thank you for listening until next time
