ABSTRACT

This work establishes the relationship that exist between incidence and deaths from diseases. In the course of the project, data on the sufferers of these diseases and the number of deaths that has occurred for a period of ten years (1991-2000) was collected from the Federal Medical Centre, Umuahia and was analysed statistically. The chi-square test of normality was carried out on the data collected, that establish the data was not drawn from a normally distributed population. Also, the test of constant variance was conducted which showed that the variance of  incidence is the same as that of death cases. Finally, in the regression analysis conducted, it was established that the linear regression analysis provided a good fit to the data. This showed that the two variables were found to significantly linearly related. Since there is a linearly relationship all efforts should be on the reduction of infection rate so as to reduce the death rate.
