Sample
Our research study aims to examine the role of single-sex schools towards ineffective inter-gender
cooperation between university students. As such, the target sample will include students from
universities in particular, from private universities.
The study sample will exclusively include participants who learned in either single sex schools or
multiple sex schools. Any participant who transferred between schools having different sexes will be
excluded from the final sample.
Particularly, data obtained from participants from single sex schools will be used to test the study’s
hypothesis that “persons who went to single sex schools have trouble cooperating with persons from
different gender” while data from participants who went exclusively to multiple sex schools will be used
as a control.
Sampling Size
Our research will use a sample of size 200. Our choice of sample follows the assumption of lowest
margin of error i.e. the choice of a sample size that will lead to the lowest margin of error and realistic at
the same time (Burmeister & Aitken, 2012).
According to Burmeister &Aitken (2012), a larger sample of size 200 is most likely to have a 0.071
margin of error which is relatively low hence suitable for use.
Sampling Method
In order to select a representative sample from the university population, we will use a purposive
sampling technique also known as selective/subjective sampling with a specific adoption of typical case
sampling. Ideally, typical case sampling is appropriate in the event that the research objective is to study
a given trend or phenomena in the target population (Crossman, 2018) as it is in this study’s case in which
the phenomena is to examine if going to a single sex school influences inter-gender cooperation among
