Educational Language
Pedagogical Use Description This is a good data set to use in a discussion of feeding "strategies," e.g., trade-offs for predators vs. herbivores. It is also useful for instruction about the use of Excel to make figures because the data set is not very large.

In regard to sampling and statistics, these data can also lead to discussion about means, standard deviation and standard error, and statistical differences. Despite the wide range in the data, piscivores were statistically different than the rest because of the large sample size. As a specific Excel skill, students could also learn how to sort with the unsorted data.
