At a casual glance, the 4-45% statistic also applies in the inverse direction, so it's fairly meaningless when discussing gender inequality.

The more appropriate statistic would be that "on average, women are offered 4% less" which seems to have been produced by integrating an estimation of the probability density, and looking at the non-symmetry of the distribution. It seems most of that difference is concentrated within 10% on the mean.

So (roughly) if you're a man, you had a 50% chance of being offered 4% more than a woman, and maybe a 30% chance of being offered 4% less than a woman.
