Wet season | Dry season | ||||
Amboseli | 2010 | 235 | 222 | Χ2 = 0.37, df = 1, p = 0.54 | For 2010, wet season and dry season numbers were similar, with wet season being non-significantly higher. |
2013 | 325 | 184 | Χ2 = 39.06, df = 1, p < 0.001 | For 2013, wet season number was higher than the dry season number. | |
Chi-square value | Χ2 = 14.46, df = 1, p = 0.31 | Χ2 = 3.56, df = 1, p = 0.059 | For the set of wet season, and dry season, buffalo numbers were similar over time (with non-significant increase in wet season, but also non-significant decline in the dry season over time). | ||
Magadi | 2010 | 62 | 63 | Χ2 = 0.008, df = 1, p = 0.93 | For 2010, wet season and dry season numbers were similar. |
2013 | 107 | 0 | No statistical test necessary | For 2013, wet season number was higher than dry season number because there were no buffalo seen in dry season. | |
Chi-square value | Χ2 = 11.98, df = 1, p = 0.001 | No statistical test necessary. | For both sets of wet season, buffalo number in 2013 was higher than for 2010 (i.e. buffalo number increased with time for both seasons). This cannot be said for the dry season because there were no buffalo in 2013 meaning a possible decline. | ||
West Kilimanjaro | 2010 | 0 | 12 | No statistical test necessary | For 2010, buffalo were only seen in the dry season and not wet season. |
2013 | 143 | 0 | No statistical test necessary | For 2013, buffalo were only seen in the wet season but not in the dry season. | |
Chi-square value | No statistical test necessary. | No statistical test necessary. | For the pair of wet season, buffalo were only seen in 2013 implying an increase with time. But for the dry season, buffalo were seen only in the in 2010 implying a decline with time. | ||
Natron | 2010 | 37 | 21 | Χ2 = 4.41, df = 1, p = 0.036 | In 2010, the buffalo number in the wet season was higher than the dry season. |
2013 | 0 | 0 | No statistical test necessary | For 2013, there were no buffalo numbers in both wet and dry season. | |
Chi-square value | No statistical test necessary. | No statistical test necessary. | For both pairs of wet and dry season, buffalo were only seen in 2010 but not 2013, implying a possible decline with time for both seasons. |
