Bongbong fixated on studying the influence of
fatigue among working students in their academic
performance. To choose his respondents, he used
purposive sampling and asked working students to
participate in his study. Was his sampling method
appropriate?
Yes, because only those who are
working students are suitable to become her respondents.
No, she should have used simple
random sampling to avoid bias.
Yes, because working students are the
only ones who are conveniently available.
No, stratified sampling is the best
method to do because he needs to group the population first before taking samples.
