Grammar
Apostrophe use
You may be familiar with the correlation coefficient, which was invented by a fellow named Pearson. There is another correlation coefficient invented by Spearman. If I wish to say: "Pearson's correlation coefficient yields 0.5 and Spearman's yields 0.6", is it correct to use the apostrophe in their names or not?

Those apostrophes are fine, but if the coefficients are actually named after the two gentlemen, then you should use these, which are valid alternatives in any case:
The Pearson correlation coefficient yields 0.5 and the Spearman correlation coefficient yields 0.6.
The Pearson correlation coefficient yields 0.5 and the Spearman correlation coefficient yields 0.6.
