In this video (13:14), Mr. Khan explains how use data in a box-and-whisker plot. Mr. Khan uses the computer software (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education.

A brief video explanation on how to create a box and whisker plot on a TI-83 or TI-84 graphing calculator. Step by step instructions are presented with text on the screen and the then the image is shown performing the step. Note that the images som...etimes flicker due to the high definition of the recording.[more]

This video shows how to make a quartile diagram using the 5 key values. An example is shown for finding 5 key values. This is geared for high school level statistics. A good, clear presentation is made using a computer software program and a curs...er moving and manipulating the data. To continue with this video on how to draw the diagram you must visit the link provided at the end of the video.[more]

Mr. Khan added another video to his discussion of Box-and-Whisker Plots. During this ten-minute video, Sal Khan demonstrates how to use Box-and-Whisker Plots. The print is small and on a dark screen, so the viewer may wish to open to 'full screen'.

Students learn to make a box-and-whisker plot for a given data
set using the following steps. This video describes, first, how to write the data set in order from least to greatest. Next, find the second quartile, which is the median for the entire ...data set. Next, find the first quartile, which is the median for the lower half of the data set, and find the third quartile, which is the median for the upper half of the data set. Next, find the least and greatest numbers in the data set. Next, draw a number line with vertical lines at the first, second, and third quartiles, and connect the endpoints of the vertical lines to make a "box". Next, plot the least number in the data set and connect it to the box with a segment, and plot the greatest number in the data set and connect it to the box with a segment, to make "whiskers".[more]

Learn how to make a 'Box and Whisker Plot in this video. The five values that are needed to make the plot are discussed. A thorough step by step example is presented on a whiteboard. (05:52)

See how to create a Box Plot or Box & Whisker Statistics chart
using a Stacked Bar Chart and a Open-High-Low-Close Stock Chart. The video show how to use the QUARTILE function and how to link Chart Labels to cells. The demonstration is done using t...he software program and the data sometimes is a little difficult on the screen.[more]
