[R] I need to compare ranking (1-15) across 10 replicates to see if the ranking changes significantly- how???
Hi there all suggestions much appreciated! so our investigation is looking into the time pairs of guppies spend interacting... we have raw data in minutes, but have ranked each possible association between pairs (out of 15 possible) in order of frequency of occurence during a 20 min recording period. then rinse and repeat 10 times... :-D so this is what we have: (rows are replicates, columns different interactions) L/L L/S L/B L/D L/LT S/S S/B S/D S/LT B/B B/D B/LT D/D D/LT LT/LT 1 12 10 3 1 8 11 6 5 15 14 7 4 8 2 12 2 4 2 1 3 5 15 13 6 12 11 14 6 8 10 9 3 12 14 8 6 2 15 12 4 5 7 10 1 11 8 3 4 7 11 1 10 4 6 5 8 12 14 13 2 9 14 3 5 4 10 2 10 12 8 7 3 6 12 14 1 14 9 5 6 2 8 9 5 13 11 12 7 6 1 15 4 13 3 10 7 3 4 6 13 11 8 2 14 12 1 14 9 10 5 7 8 2 9 3 5 1 5 4 10 15 11 13 12 7 7 14 9 5 6 1 9 11 13 4 10 3 8 13 2 15 7 12 10 3 11 9 15 7 10 6 4 8 1 13 2 12 4 14 Score 54 85 43 77 74 102 71 71 94 80 126 43 107 69 89 Ranking 3 10 1 8 7 13 5 5 12 9 15 1 14 4 11 is it possible to run an ANOVA on this, to assess the stability of interactions? With the idea that if the ranking changes a significant amount between replicates, associations are not being maintained...?? all help and advice gratefully received!
