3.4. Study population
William fox (1992:06) defines population as «a set of
cases from which a sample is drawn and to which a researcher wants to
generalize». He continues by asserting that population is data pertaining
to all or almost all cases to which a researcher wants to generalize.
For any study to succeed, information needs to be
representative of the population covered by the research questions. A
population refers to the total number of elements covered by the research
questions (Scott, I et al 1998:307). «Population can be defined
as the totality of persons or objects with which a study is concerned».
Grinnell et al (1990:118).
Christensen (1991:101) asserts that, population refers to all
the events, things or individuals that are the objects of investigation. This
research is made to study the relationship between small and medium enterprises
and rural development in Rwanda, thus the researcher surveyed a selected unit
(enterprise) technically determined. The population under study was comprised
of stakeholders of enterprise.
3. 5.Sample size and selection techniques
The study must consider a sample size that is within the cost
constraint but should provide the ability to detect an independent variable
effect (Christensen, 1991: 372). Williamson (1982:113) comments on the sample
size as being a phase of research, which is crucial because of its major impact
on time and money that must go into data collection.
While selecting the sample size of the study; the researcher
purposely five respondents particularly; representing all staff members. Data
is collected from selected respondents from the study population due to the
reasons of necessary and convenience.
3. 5. 1 Simple random sampling
Simple random sampling was be used to select the institution.
Simple random sampling as defined by Baker (1988:148) refers to the situation
whereby each individual case in the population theoretically has a chance of
being selected for the sample. The simple random sampling technique was used to
select local entity.
According to Bailey (1978:70) a sample size is a subset or a
portion of the total population to be studied. The study mainly deals with the
impact of organizational communication in enhancing work effectiveness of local
government entity of Tumba Sector. In the study, two categories of respondents
were selected (leaders and citizens). Due to the limitation of financial means
and time at the disposal of study, for the purpose of convenience and
appropriateness, it is not possible to reach the whole population of
TUMBA Sector. Thus, the data will be collected from the
selected respondents to generalize the result of the study. In my research, the
interview will be applied within three villages of Tumba Sector among the six
of the whole Sector; I will randomly query any citizen randomly fifteen people
including three leaders and or more
3. 6. Data collection methods and instruments
The information from the primary data was obtained through a
structured questionnaire and an interview schedule and documentary search was
applied as to obtain secondary data.
