Your bra size could determine how much you spend Bigger than a B cup? Better watch your bank balance. YOU'VE heard of Big Data, right? Even if you don't quite get it (and really, who does?), you probably understand, to some degree, that Big Data means that companies, governments and organisations have loads of information on you which can be used to build a profile of you. Retailers love Big Data because once they can make sense of it all the information nuggets consumers have littered around the place, it gives them information on how to make more money. And one of the weirdest examples yet of Big Data we've seen has to do with bra sizes and spending power. Chinese e-commerce giant Alibaba crunched the numbers and found a correlation between bra size and how much that consumer spends, according to a report in Quartz. Essentially, customers who bought bras with a cup size of B or smaller tended to spent more. And the closer you got to E cup, the more likely you were to part with more dosh. Quartz suggested there could be any number of reasons why this is including that younger women have a lower buying power. Alibaba, which recently made almost $AU10.7 billion in just one day of sales, has indicated it will dedicate significant resources to data mining and gaining insights from the reams of information. Amazon, of course, has been an enthusiastic subscriber to Big Data with many functions on its site based on what it knows about you and your purchase preferences. Who knows what data mining will find out next? That men who buy purple French-cuffed shirts are more likely to order scallops for an entree? We made that last one up.
