Macmillan Learning Phytopigments are markers of the amount of organic matter that settles in sediments on the ocean floor. Phytopigment concentrations in deep-sea sediments collected worldwide showed a very strong right-skew. Of two summary statistics, 0.015 and 0.009 grams per square meter of bottom surface, which one is the mean and which one is the median? The mean is and the median is Choose the best explanation for your choice. Because the distribution is strongly right-skewed, we expect the median to be larger than the mean. The median is always larger than the mean. The mean is always larger than the median. Because the distribution is strongly right-skewed, we expect the mean to be larger than the median.
