The article “Hydrogeochemical Characteristics of Groundwater in a Mid-Western Coastal Aquifer System” (S. Jeen, J. Kim, et al., Geosciences Journal, 2001:339–348) presents measurements of various properties of shallow groundwater in a certain aquifer system in Korea. Following are measurements of electrical conductivity (in microsiemens per centimeter) for 23 water samples. 2099 528 2030 1350 1018 384 1499 1265 375 424 789 810 522 513 488 200 215 486 257 557 260 461 500 Find the mean. Find the standard deviation. Find the median. Construct a dotplot. Find the 10% trimmed mean. Find the first quartile. Find the third quartile. Find the interquartile range. Construct a boxplot. Which of the points, if any, are outliers? If a histogram were constructed, would it be skewed to the left, skewed to the right, or approximately symmetric?
