Fig. 10From: Development of a spatial sampling protocol using GIS to measure health disparities in Bobo-Dioulasso, Burkina Faso, a medium-sized African cityAnalysis of the spatial distribution of the households surveyed in each district by the Ripley’s K function. When the observed K-value (in red on the graphic) is higher than the expected one (in blue on the graphic) for a particular distance, the household distribution is more clustered than the random distribution at the considered distance. When the observed K-value is lower than the expected one, the household distribution is more dispersed than the random distribution at the considered distanceBack to article page
