Statistical analyses

The number of bee lines per feeding station can be analysed by an assigned independent variable using a weighted one-way ANOVA. The ANOVA is weighted for the number of feeding stations within an independent variable. For example, Vaudo et al. (2012b) looked at land use effects on the number of bee lines, with land use being recognized as stations on (1) game reserves or (2) livestock farms. Since the authors did not place the same number of feeding stations at locations of both types, the ANOVA analyses were weighted for the number of feeding stations used, giving greater weight to sites having more stations. The field and photograph indices of numbers of bees at feeders can be analysed by Pearson’s χ2 tests to determine if there is a difference in the distribution of ratings between feedings stations categorized in two or more independent variables.

Pros: this is a relatively inexpensive method.

Cons: time consuming, reliability not established.
