Description:
The data are represented graphically in the usual form of "box and whiskers". This is a highly simplified representation of a distribution, which is very useful for comparing data or checking their aspect (balanced or not, concentrated or spread out, symmetrical or not, etc.):

  • The edges of the box correspond to 25% and 75% of the samples (quartiles).
  • The box is divided at its median (50% of the samples).
  • The ends of the whiskers correspond to the samples situated (1.5 times the box size) outside the box.
  • If the distribution contains points outside the whiskers, these exceptional points are shown as short vertical lines.

All the boxes and whiskers are drawn on the same graph on the same scale. The scale varies from the minimum data value to the maximum data value. If the window size is modified, the drawing is automatically adapted to the new size.

The name of each data input is displayed to the right of the corresponding box, together with the Input field.

Possible actions:

  • By moving the mouse on the drawing, the value pointed by the mouse is posted.
  • By notching the name of a data in the zone Inputs, a complete statistical summary of the selected distribution is posted :

  • If the data are moved vertically in the Input field, the order of the boxes and whiskers is changed immediately in the graph. This enables you to put data next to each other as you wish, in the order you have decided on.

Graphics :
Under the graphic, you will find a button : that creates a "graphical window" from current drawing. This window let you compare graphics, export them, or print them.
