Comparing the biodiversity of three plant communities Data Collection: Below are three tables showing the number of species found in each quadrat in each group. Site 1: Waste ground on the edge of the park Quadrat Group 1 2 3 4 5 1 4 5 3 5 4 2 6 6 7 4 6 3 4 3 6 3 5 4 5 6 6 3 6 5 5 5 3 3 3 Site 2: Lawn in the park Quadrat Group 1 2 3 4 5 1 5 4 3 3 5 2 4 2 4 5 4 3 5 4 4 3 3 4 4 4 3 2 2 5 2 3 4 3 3 Site 3: Edge of football field Quadrat Group 1 2 3 4 5 1 2 3 4 1 3 2 5 2 2 3 2 3 4 6 4 5 5 4 1 2 2 2 1 5 2 4 3 3 3 * The sum of the species found in site 1 is 116. Therefore the average species found in this area can be calculated by sum divide by the number of sampling (25), 116/25=4.64 species. * The sum of the species found in site 2 is 88. Therefore by the same method as above, its average is 88/25=3.52 species. * The sum of the species found in site 3 is 74. Therefore by the same method as above, its average is 74/25=2.96 species. * Standard deviation can be calculated by: Therefore, the standard deviation for the site 1 is 1.261110622, for the site 2 is 0.9431860898 and for the site 3 is 1.341044369. * From...
