Test of Homogeneity of Variance among Regional Climatic Variables Using Stratification Process

Abstract

This paper examines the homogeneity of variance among the regional climatic variables using stratified process in computing the weighted mean and variance. It also determines effects of covariance on climate change using Gaussian-seidel method . Its measure the  rate of change on average regional temperature and its effects on climate change in Nigeria. Our finding indicates that there are variations in average temperature in all the regions due to temporal and spatial variation associated to weather conditions, these  influence the persist increase in average regional temperature in Nigeria. The Sahel and Guinea savannah contribute more to persistence in climate change due to extreme weather conditions associated to the two regions.
