A five-number summary describes a numeric distribution through its minimum, first quartile, median, third quartile, and maximum. In pandas, describe() returns these values alongside the mean and standard deviation. section 11.4
Read the summary of a Series
For s = Series([10, 15, 17, 20, 25]), s.describe() reports 10 as the minimum, 15 as the 25% quartile, 17 as the median, 20 as the 75% quartile, and 25 as the maximum. The same output also reports count, mean, and standard deviation. section 11.4
s.plot.box()
Run s.plot.box() to display the five-number summary graphically: the box marks the quartiles and median, while the whiskers extend to the minimum and maximum. section 11.4
Boxplots also make unusual observations visible. In pandas, points at least 1.5 times the interquartile range below the first quartile or above the third quartile appear as outliers. section 11.6
