• Median (Q2)
• interquartile range 50% of all the data point are within this range.
• Bottom box (Q3) above this value are 7% of all the data points
• Bottom wisker: Bottom box (Q3) - 1.5 x interquartile range (Q1-Q3)
• o outliers between 1.5 and 3 times the interquartile range
• + extreme outliers above 3x the interquartile range
