DATA SETS

There are three Excel datasets: Dataset Number 1, Dataset Number 2, and Bonus Data. There is also a Species List, including the scientific and common names of the species included in the experiment.

Dataset Number 1 contains average plant biomass and standard errors for each species richness treatment for seven years. This dataset allows students to explore the relationship between species richness and plant productivity.

• Dataset 1 – Student
• Dataset 1 - Faculty

Dataset Number 2 shows the percentage of plots that exceeded the maximum monoculture biomass and allows a test of the sampling effect hypothesis.

• Dataset 2 – Student
• Dataset 2 - Faculty

The “Bonus” Data presents data from all 168 plots, including the presence/absence of functional groups. We have included this richer data set as an opportunity for teachers and students to be creative and have therefore left the exercise quite open-ended.

• Bonus Data – Student
• Bonus Data - Faculty

Species List shows the functional groups, genera and species, and common names of plants.

• Species List

Note: each year new data from this experiment becomes available on the webpage (http://www.cedarcreek.umn.edu/research/exper/e120/). Instructors may choose to have students find and incorporate this data as part of their exercise.
