GROUP 3
DATA
COLLECTION
Snowball Sampling was employed
as the group reached out few
students from each year level and
let those students relay the google
form to their classmates via their
respective Group Chats.
SNOWBALL SAMPLING is a sampling method used by
researchers to generate a pool of participants for a
research study through referrals made by individuals
who share a particular characteristic of research
interest with the target population (Frey, 2018).
GROUP 3
DATA
COLLECTION
The survey targets 25 respondents
each from 1st year to 3rd year and
15 respondents from 4th year.
QUOTA SAMPLING is defined as a non-probability
sampling method in which researchers create a sample
involving individuals that represent a population
(QuestionPro Survey Software, 2022).
GROUP 3
DATA
COLLECTION
To finally obtain the target
number of respondents, simple
random sampling technique was
used through ‘Wheel of Names'
method which was done per year
level.
SIMPLE RANDOM SAMPLING is a
randomly selected subset of a population.
In this sampling method, each member of
the population has an exactly equal chance
of being selected (Thomas, 2020).
