Detailed explanation-1: -A box and whisker plot-also called a box plot-displays the five-number summary of a set of data. The five-number summary is the minimum, first quartile, median, third quartile, and maximum. In a box plot, we draw a box from the first quartile to the third quartile.
Detailed explanation-2: -A summary consists of five values: the most extreme values in the data set (the maximum and minimum values), the lower and upper quartiles, and the median. These values are presented together and ordered from lowest to highest: minimum value, lower quartile (Q1), median value (Q2), upper quartile (Q3), maximum value.
Detailed explanation-3: -Collect and organize your data. Calculate the median. Calculate each of the quartiles. Create your plot line and draw a line for each of your quartiles. Create a box connecting the quartiles. Find the interquartile range. Find the new upper and lower limits. 07-Oct-2019
