Measures of center include the mean or average and median the middle of a data set. The line across the box shows the median score for the data set.
Draw a box from the first quartile Q1 to the third quartile Q3 Then draw a line inside the box at the median Then draw whiskers from the quartiles to the minimum and maximum values We can determine whether or not a distribution is skewed based on the location of the median value in the box plot. A Box and Whisker Plot or Box Plot is a convenient way of visually displaying the data distribution through their quartiles. 25 is before the box and 25 is after the box. In this example arrange the points scored per game from least to greatest. A box and whisker plot is defined as a graphical method of displaying variation in a set of data.

A box and whisker plot is defined as a graphical method of displaying variation in a set of data. The box plot is comparatively short see example 2. It is also used for descriptive data interpretation. The whiskers also represent 50 of the data. 25 is before the box and 25 is after the box. Simply expressed the lower whisker represents the bottom 25 of scores the box represents the middle 50 of scores and the upper whisker the top 25 of scores.
