The relationship was so striking that, according to the rules of maths that govern such things, you could say with great confidence that the results were very unlikely to be merely random. Such a relationship is said to be ?statistically significant?. But the Dutch folklore of the time that storks somehow increased human fertility was clearly wrong.”
