A box plot gives us a visual representation of the quartiles within numeric data. The box plot shows the median second quartile first and third quartile minimum and maximum. The main components of the box plot are the interquartile range IRQ and whiskers.
A boxplot is a visual representation of the five number summary of a data set. The five number summary of a distribution is an alternative to using the mean and standard deviation to describe the distribution. Recall that the five number summary consists of.
The maximum and minimum values the interquartile range IQR and the median. The boxplot is credited to John W. The boxplot is simply a summary of five numbers from the data set.
The median is the line dividing the box the upper and lower quartiles of the data define the ends of the box. The minimum and maximum data points are drawn as points at the ends of the lines whiskers extending from the box. Boxplot is one of the plots which is the culmination of statistical data with visualization to make effective observations.
