In descriptive statistics, a<unk>  (also known as a<unk> -and-whisker diagram or<unk>  or candlestick chart) is a convenient way of graphically depicting groups of numerical data through their five-number summaries (the smallest observation, lower quartile (Q1), median, upper quartile (Q3), and largest observation). A<unk>  also indicates which observations, if any, might be considered outliers. The<unk>  was invented in 1977 by the American statistician John Tukey.<unk> s are able to visually show different types of populations, without making any assumptions of the underlying statistical distribution. The spacings between the different parts of the<unk>  help indicate variance, skewness and identify outliers. <unk> s can be drawn either horizontally or vertically.
