Scenario 3-Pollinator Flower Preference Experiment Ms. Barksdale's seventh grade class is studying the association of insect species to different odors around their school property. Students were assigned one of four odor stations to observe around campus (rotten peach, manure, dead mouse, rotten egg). They were instructed to observe their scent station and record the number of visits for each of four different insects (beetles, wasps, flies, moths) during a one-hour observation period. After all students groups had collected their observations, a total count of each insect type on each scent station was summarized on the board. The students hypothesized (H) that due to differences in the resources represented by different odors that different insects would likely visit different scent stations. Both the variables in this experiment are categorical with scent stations having 4 levels and insect visitors having 4 levels. The data are counts which can be summed for each of the 16 possible combinations of scents and insect types. The null hypothesis (H) is that the ratio of insect types at each station is of equal proportions.
