process<strong>in</strong>g and analysis. <strong>The</strong> essence is to put the data <strong>in</strong> contextual form to enable the<br />

researcher answer the research questions as well as address the research objectives.<br />

Consequently, quantitative analysis us<strong>in</strong>g simple tables, bar charts, percentage distributions and<br />

statistical analysis were carried out <strong>in</strong> order to establish the relationships between various<br />

variables. Abdullah (2004) noted the need to ensure that the follow<strong>in</strong>g steps were taken:<br />

• That the tables and diagrams have brief and clear descriptive title.<br />

• That the units <strong>of</strong> measurement are clearly stated.<br />

3.1.9: F<strong>in</strong>al Model Used <strong>in</strong> Regression<br />

<strong>The</strong> study uses the follow<strong>in</strong>g model to capture the impact <strong>of</strong> SACCOs on <strong>in</strong>come <strong>of</strong> the<br />

poorest 20 percent households <strong>in</strong> Tanzania... <strong>The</strong> model is derived and as a s<strong>in</strong>gle equation<br />

l<strong>in</strong>ear model expressed <strong>in</strong> log l<strong>in</strong>ear form, as specified below:<br />

Grate 20% In poor= C+ (1-G) RGDP rate + GSS rate + SL rate + DMF+ e<br />

C = Constant term<br />

G rate 20% <strong>in</strong> poor = Growth rate <strong>of</strong> nom<strong>in</strong>al private <strong>in</strong>come received by poorest 20%<br />

households <strong>in</strong> Tanzania.<br />

RGDP rate= Real Growth Domestic Product Rate.<br />

GSS rateI= Growth rate <strong>of</strong> Government Investment <strong>in</strong> Social services.<br />
