My final field data was collected using a stratified random sampling strategy whereby 40 1 square metre quadrats were measured along the northern and southern ends of Grenadier Pond. Of these 40 quadrats, 10 were to have high densities of phragmites (x > 50 stalks per square metre), 10 were to have moderate densities of phragmites (10 <= x < 50 stalks per square metre), 10 were to have low densities of phragmites (0 < x < 10 stalks per square metre), and 10 were to have no phragmites (x = 0 per square metre). All 40 quadrats were controlled to be invariable for other possible confounding variables, including elevation, soil type, and overall species richness. In each of the stratifications (i.e. discrete phragmite density categories), the total stalk density of native broadleaf cattail per quadrat was observed and recorded. The table that I created and submitted reports the mean broadleaf cattail stalk density per discrete phragmite density category. It looks like this:
I had no particular difficulties organizing, aggregating, or summarizing this data; it involved a simple calculation of sample means per phragmite density category, taken directly from my field data submitted as Submission 4. The outcome was largely as I expected; the sample means differed significantly from each other, except in between low and none (82.3 vs 87). This suggests that when phragmite density is sufficiently low, cattails are not affected to any significant degree by interspecies competition. This can be confirmed with a Tukey’s HSD test in my final report.

you can use the text section to provide some detail and background to the reader – a few sentences if you would like – think of it as ‘free’ space to explain more about what you are doing!
