    Statistics Example #1 Graph

    Thumbnails for each column in the analyses are shown in a box and whisker plot. The “box” is comprised of a green dot within a blue rectangle. The dot represents the mean value, while the rectangle itself represents plus/minus one standard deviation from the mean. Two “whiskers” are drawn from minus one standard deviation to the minimum value, and from plus one standard deviation to the maximum value.

    As the mouse passes over each thumbnail, the cursor changes to indicate a hyperlink, and the individual graphs can be maximized by clicking on the thumbnail:
