The population of the study comprised
of visually impaired people who were currently
studying at ODL institutions or had recently
completed their programmes of study at ODL
institutions. It also involved officials from ODL
institutions. It was not possible to study the whole
population hence there was need to sample.
Convenience sampling was used to select the sample.
Convenience sampling makes use of individuals who
happen to be available at the time (Miles, 2000). This
was done to avoid challenges of entrusting a
questionnaire to a friend, relative, or colleague who
may misplace or forget to handover the questionnaire
to the targeted respondent. The sample comprised of
individuals with visual impairment and officials from
the institutions such as lecturers. Respondents also
took part on their own volition. Confidently was
guaranteed since it involved dealing with individuals.
Anonymity of respondents was also guaranteed. Data
analysis was also done in accordance with the
interpretation thereof.
