Comparison of methods to estimate water access: a pilot study of a GPS-based approach in low resource settings

Table 3 Comparison of measures—time spent and distance traveled

	Measure 1	GPS-based measure
Minutes spent per roundtrip including queue/fill time, mean (SD)^a	66 (39.1)	18.5 (24.7)
Meters traveled per one-way trip, mean (SD)^b	335.1 (267.5)	397.8 (345.5)
Meters traveled per one-way trip, mean (SD)^c	174.4 (86.5)	397.8 (345.5)

All differences were significant at the p = 0.05 level
^aMeasure 1 = Self-reported; Wilcoxon signed rank test used
^bMeasure 1 = GIS Euclidean distance to primary source; Wilcoxon signed rank test used
^cMeasure = GIS Euclidean distance to nearest source; Wilcoxon signed rank test used
