Testing the Pearson’s r of 0.2706 for these data indicates that this isn’t a significant correlation (if the fact that it looks like a shotgun blast didn’t convince you in the first place). In desperation, you might even see if the number of complaints is a leading indicator and correlate it with future sales, but (since I made up these data) that turns out to be fruitless as well. And you get the fun job of explaining to the CEO that his or her favorite metric is, in fact, bogus, at least in terms of making the company money.
