by arranging and organizing them properly so as to be easily interpreted. To
analyze data the researcher used editing, coding and tabulation.

The ultimate purpose of editing was to discover or to monitor
the accuracy and to detect gaps and other weaknesses in the data and collection
methods. Here the researcher will make sure that all the questionnaires were
fully answered and returned to him. Maximum care will be taken in the process
of sorting out the unnecessary information so as not to distort the message
from the respondents.
3.4.2. Tabulation
Tables with corresponding calculations were used to indicate
the frequency of particular answers. Percentages also were used to express the
data in a ratio form. For making the data easily and clearly understood, each
table was followed by small explanation of the nature of relationship indicated
in the table.
3.5. Data analysis
Data were analyzed after editing, coding and tabulation. This
analysis was based on percentages that were obtained to show the relationship
between the study variables. The information was summarized according to the
objectives of the study.

The hypothesis of the study stated that, `Commercial Banks can
contribute to the development of trade in rural areas'. The aim of this
hypothesis was to show the role played by BPR S.A KADUHA Sub-Branch in
promoting trade in the area under the study. The hypothesis was tested basing
on respondents views. Testing the hypothesis means that the analysis of data
either supports or rejects the hypothesis. The researcher tested the hypothesis
quantitatively basing on the opinions of several respondents to whom
questionnaires were distributed.
