A few days ago I finished collecting all the z-scores, skewness levels, and kurtosis levels for physical damage and disease prevalence within the Hawaiian Coral Reefs. I ultimately decided not to look into deaths considering I already had a lot of data to look at. So instead I’m going to compare damage and disease in terms of how much harm has come to the colonies in the coral reefs.
So far, what I’ve found by looking at my results is that none of the distributions are normal. The fact of the matter is that all of my distributions are skewed to the right, and even after taking out larger outliers that fall outside of 3 standard deviations of the mean, the distributions still appear to be skewed.
Though I did find some interesting data points within the results, specifically a majority of the z-scores had been below the mean, and only a handful were above the mean. And of the z-scores that were above the mean, only one of them was not above 0.05. Considering that there are 69 organisms and about 19 are significant, I believe it is safe to say that those 19 are what I will be focusing on in my analysis.
