No, as the sidethread comment notes, there is only one way you can compute quartiles. You seem to be arguing that the correct thing to do is to impute them, and that calculating them is such a deviant practice that it would need to be specially remarked on.

Isn't this what i was saying from the beginning?

  Box plots are made for visualizing generalized normal distributions and nothing else.

And now people in this thread argue you can calculate them from something else. Not sure if you are replying to the right post.

That might be what you were saying from the beginning, but the only thing that that would establish is that you're completely out of touch with reality. Box plots are made for visualizing quartiles.

Your theory would imply, among other things, that the median line going through the box part of a box plot always divides it in half, which obviously is not the case.

No? Exponential Gaussian?

Whatever you do, you should explain first what you do that your whiskers stay meaningful and are not just whatever randomness your outliers produced.
