1. Chi Square Analysis for insects trapped on Pitcher Plant
... the pitcher plant leave prominently for nectar. This gives us and inverse relationship between the feeding times of the two insect groups. Chi square operates by comparing the actual, or observed, frequencies in each cell in the table to the frequencies we would expect if there were ... = 3.33 Late Evening Diptera (flies) = ((10 - 20)2/20) = 5 Evening Coleoptera (beetles) =((20 - 30)2/30) = 3.33 Late Evening Coleoptera (beetles) =((30 - 20)2/20) = 5 Total Chi Square for table = 16.66 To interpret this value we need our degree of freedom (df) expressed by the following formula: df = (r-1)...
