22.214.171.124. Statistical analyses
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.
