Why is it important to understand how disturbance impact ecological communities? 9. Conduct an analysis of species richness between quadrat 1 (High disturbance) vs quadrat 3 (Intermediate Disturbance). To do this, evaluate normality using a Shapiro-wilks test followed by an appropriate paired sample test. This is the same analysis completed in lab 3. a. Report the results of the Shapiro-wilk test (W test statistic and p-value). Does your data meet the normality assumption? What paired test did you use? b. Report the results of your paired test. Include the V test statistic (if you ran a Wilcoxon signed rank exact test) or t statistics (if your ran a paired t-test) with the p-value. c. What is your conclusion about the effect of quadrate location on species richness?Raw Data gathered from transect sampling plant species on campus of Francis Marion University.
