Brainlet here, what does it mean if something correlates with something that follows a bell curve with " .x "

For example, let's say a standardized test like the LSAT has a correlation with the WAIS IQ test of .75. What does that mean exactly? If someone get's 2 standard deviations above the mean in the LSAT does that imply that his IQ is likely to vary from 1.5 to 2.5 standard deviation (+/- 0.5) in the WAIS test?

>Bismarck, Luther, Laplace, Napoleon, Pascal, Raphael, Beethoven, Haydn, Schubert are examples of brachycephalic types, or even hyperbrachycephalic ones. Hyperbrachycephalic types have an Index starting at 85 . Schiller's skull has an Index of 84 and is thus on the border of hyperbrachycephalicy, Kant with an index of 88.5 was a definite example of one. Hamerling had an index oc 85.3, Schopenhauer one of 86, and Leibniz one with 90.3.
