Blog Post 5: Design Reflections
It was difficult to measure different sample area, every time I observed. Each area, preserved hill, ornamental steps, ornamental gardens were not really huge, randomly selected quadrat easily overlapped the area that I already observed, which increases error in data accuracy. Therefore, I though it might have been better if it followed systematic sampling techniques rather than random sampling technique. Also, in preserved hill there was not much dry/green grass, barely any vegetation could be seen. In ornamental steps green grass did not exist however, green clover was easy to observe. Although there were a lots of points that were missing however, the results quantitatively supported my hypothesis that there were more fresh plants observed as the landscape was more intervened with artificial modification.
To make more accurate, credible and supportive data I would make several changes. First, I will change my sampling technique from random to systematic. Also, considering the environment there might not be an vegetation the denominator will be the area of the quadrat 100 cm^2. Finally, considering other species of vegetation exists, I would change the numerator will be changed to the green surface area in that quadrat. This will test more closer to the hypothesis I was about to test, also it will reduce the error, and the conditions of sampling is more refined to support the hypothesis.
