The Effect of Light Intensity on Sarcophaga sp. Appendix Test Name : Wilcoxon Signed Rank Test Compares : The mean displacement of Sarcophaga larvae at 0.00 u mol m -2 s -1 and 50.04 u mol m -2 s -1 . Individual 0.00 u mol m -2 s -1 50.04 u mol m -2 s -1 Difference (d) Rank |d| 1 4 7 -3 (-) 4 2 3 9 -6 (-) 7 3 7 4 +3 (+) 4 4 1 4 -3 (-) 4 5 11 15 -4 (-) 6 6 5 11.5 -6.5 (-) 8 7 11 21 -10 (-) 9 8 1 3 -2 (-) 2 9 1 13.5 -12.5 (-) 10 10 0 1.5 -1.5 (-) 1 H o – There is no difference between the measurements in the two groups H a – There is a difference between the measurements in the two groups. T + = 4 Test Statistic = 4 T - = 51 Tabular Statistic (α = 0.05, n = 10) = 8 n =10 Conclusion Test (4) < Tabular (8), therefore reject H o and conclude that the differences between the two groups of data (0.00 u mol m -2 s -1 and 50.04 u mol m -2 s -1 ) are statistically significant at α = 0.05 Test Name : Wilcoxon Signed Rank Test Compares : The mean displacement of Sarcophaga larvae at 0.00 u mol m -2 s -1 and 100.02 u mol m
