Correlation and coefficient of variance among habitat types and seasons.

Habitats (blocks)		Seasons						Habitats (strata)	Seasons	No. of waterbucks spotted	Population (N)	Mean	Standard deviation (SD)
				Wet season			Dry season
				No. of groups	Group size range	Group size mean	No. of groups	Group size range	Group size mean
Habitats (strata)	Grassland	3	13	9.67	6	2	2.33	130	2.4		1.2
	Wetland	3	2	2.67	3	3	5.00
	Scattered vegetation with bush land	4	4	5.25	3	0	3.00
	Riverine forest	2	7	5.50	3	11	7.67
	Pearson correlation (r^2)									1		−0.19	0.64
	Coefficient of variation (covariance)									1.44		−0.12	28.75
Seasons		Pearson correlation (r^2)						−0.19	1	−0.86	130	1.5	0.5
				Coefficient of variation (covariance)						−0.12				0.25	−16.31
No. of waterbucks spotted		Pearson correlation (r^2)						0.67	−0.87	1	130	65.5	37.7
				Coefficient of variation (covariance)						28.75				−16.31	1419.17

Correlation is significant at the 0.01 level (two-tailed). Correlation is significant at the 0.05 level (two-tailed).
