If you knew just enough to be totally ignorant, you'd realise that those charts ("Mars in the charts of military career people - 158") are totally meaningless. Correlation is a number that varies between 1 (totally related) though 0 (totally unrelated) to -1 (exactly the opposite). It never has values like 158.

To get a correlation, you'd need all the start signs of the military types, and plot them out. If you found that over huge numbers of people, they were all in, say, Mars or thereabouts, you'd be justified in claiming a high correlation. If very few appeared in Mars, that would be interesting too, as although it would contradict the astrological prediction, it would show a different prediction- that astrology had something in it, even though it was interpreted wrongly. But my bet is that the numbers would be spread almost evenly over the year.
