CEVAP:

A variety of graphical techniques can be used to give an effective visual information of key descriptive statistics and the shape of the distribution for a data set. A box plot, which is also called box-and-whisker plot, is the one of these plots. In a box plot, a rectangle (box) with upper and lower edges at the 25th (Q1) and 75th (Q3) percentiles is drawn with a line in the box at the 50th percentile (Q2). Lines, which is also called whiskers, are drawn from the box to the highest and lowest values that are within 1.5xIQR of Q3 and 1.5xIQR of Q1, respectively.
