Systematic sampling was slightly faster than the other sampling techniques – taking a total of 12 hours & 4 minutes. Whereas both the random and haphazard sampling techniques took a total of 2 hours & 41 minutes. This is likely because the quadrats in the systematic sampling technique are laid out in a linear transect, which potentially reduces the amount of time that is spent walking between quadrats.
The percent error of the different strategies for the 2 most common species, Eastern Hemlock & Sweet Birch and the 2 least common species, Striped Maple & White Pine, are outlined in the attached table. The random sampling technique was the most accurate of the strategies, as it had the lowest percent error for all species. For all of the sampling strategies, the accuracy was on average higher for species that were more common in the study area, than less abundant species.
You can make tables right in your blog posts to save downloading a file and for some reason I had trouble with your file.
Was one particularly worse for the less common species? Did you notice any patterns across all sampling techniques when it came to less common species?
