STATISTICAL ANALYSIS ON ASSESSMENT OF TREATED WATER DISTRIBUTION IN KADUNA STATE (A CASE STUDY OF WATER BOARD/KADUNA STATE BUREAU OF STATISTICS, 2014 – 2023)
Abstract
This project work titled "The statistical analysis on assessment of treated water distribution
in Kaduna state", A case study of Kaduna State Water Board and Kaduna State Bureau of
Statistics. The objectives of the study are: to examine if there's significant difference between the
mean of annual litre of treated water and projected population of Kaduna state, to determine if
there's significant relationship between annual per capital, projected population and annual
distribution of water and to fit a regression model that estimate annual per capital. The statistical
tools employed are Independent sample t-test and Multiple regression analysis. Independent
sample t-test reveal a substantial and statistically significant difference between the mean annual
distribution of water and the mean projected population with p-value = 0.000 < 0.05, this implies
that adequate quantity of water is not distributed for the people of Kaduna state. The multiple
regression model demonstrated high explanatory power, with an Adjusted R Square value of .993,
indicating that approximately 99.3% of the variation in annual per capital can be accounted for by
the included predictors. The ANOVA results confirmed the overall significance of the model, with
an F-statistic of 668.109 and a p-value of 0.000 < 0.05. this implies that the model is fit for
prediction. The unstandardized coefficients provide specific insights into the impact of each
predictor, where a one-unit increase in projected population leads to a decrease of 0.000 units in
Annual Per Capital, and a one-unit increase in annual distribution of water results in an increase
of 0.116 units, both the constant and predictors, projected population and annual distribution of
water, are statistically significant (p-value = 0.000 < 0.05). To improve treated water distribution
in Kaduna State, a comprehensive strategy is recommended, involving Enhance water resource
management strategies, review infrastructure development, and optimize distribution processes to
address the challenges posed by fluctuating trends, ensure sustainable water supply for the growing
population, and improve overall access in Kaduna State.
