Unhealthful Smog Days A modified boxplot can be drawn by placing a box around Q1 and Q3 and then extending the whiskers to the largest and/or smallest values within 1.5 times the interquartile range (that is, Q3 _ Q1). Mild outliers are values between 1.5(IQR) and 3(IQR). Extreme outliers are data values beyond 3(IQR). For the data shown here, draw a modified boxplot and identify any mild or extreme outliers. The data represent the number of unhealthful smog days for a specific year for the highest 10 locations. 97 39 43 66 91 43 54 42 53 39 Source: U.S. Public Interest Research Group and Clean Air Network.
