Chi-square testing will confirm this if you feel it's really necessary--but only the Vespidae even deserve a test due to the small counts. (You will find a p-value around 0.33% for that. The usual $\chi^2$ approximation is suspect but it's not too bad: it will give you a p-value of 0.44%.) | |

| Apr 14, 2017 at 20:47 | comment | added | whuber♦ | A properly applied $\chi^2$ test will demonstrate that there are preferences. (The null hypothesis of no preference is not the same as no difference in patterns among the species, and has different expected values.) But why do that? You have four species and four tests to conduct. Is there any aspect of your data collection that suggests the results among the species are interdependent (such as competition among them for available nests)? | |
