Fig. 5.11 Random sampling grid and quadrats of different shapes (each 1 m 2 in area)
At each set of random coordinates, assess the number of stems of each species
within quadrats of all shapes, and record in the table below. As always, remember to
avoid stepping within the plots.

Data Summary and Analysis
1. There were two response variables in this exercise: plant population density and
spatial pattern. What was the independent variable?
2. Using the class data and spreadsheet program, prepare a table that contains the
means, standard deviations, and standard errors for number of stems/m 2 for each
of the shapes. Also include the sample size that you are using in each calculation.
Discuss whether these results seem to match expectation. If you assessed two
species, then create two different tables. Do not forget to include units!
