Monica The simplest solution to your problem is to use probability paper. If you do not have easy access to this, you can download a free graph paper plotter from http://perso.easynet.fr/~philimar
There are also simple algorithms to produce your own. Two populations show up on a probability plot as a line with a definite 'kink' in it. Skewed distributions should be plotted on a logarithmic scale. Explanations can be found in my paper ROKE paper (C&G 1977) which is computer oriented or in my IMGC paper (1993). Both downloadable from http://uk.geocities.com/drisobelclark/resume/Publications.html Isobel ________________________________________________________________________ Download Yahoo!
