Chlorine Concentration (ppm): 0.89, 0.9, 0.91, 0.95, 0.95, 0.97, 1, 1.04, 1.05, 1.06, 1.08, 1.11, 1.13, 1.14, 1.34 a) Find the five-number summary: Min: Q1: Median: Q3: Max: b) Find the range. c) The interquartile range (IQR) (literally stands for "the range between the quartiles") represents the spread of the middle-half of the data (rather than the range, which is the total spread of the data). The name gives away how to calculate it. Since it is the "range between the quartiles", just subtract Q3 and Q1 to find the IQR. IQR: d) Summary sentence: The chlorine concentrations, based on this sample, are centered about a median of ppm (representing a typical pool), and the middle-half of chlorine concentrations are spread over an IQR of ppm.
