> 82% of people who suffer from blood clots, sat for a significantly greater amount of time than the remaining 18%.

What? So of the group, who all had blood clots, a load of them sat more than the others? I'm struggling to draw a firm conclusion from that. What are you comparing that ratio to? If you picked a group of 100 people at random and found out how long they sat for, do you think it is likely or unlikely that 80% of the group sat more than the other 20%? If I bought 1,000 apples, and their size had a normal distribution, I could cut that distribution whether I want and thereby show that 80% of them are larger than the remaining 20%. I could say it and I would be right, but I've demonstrated nothing significant.

I'm glad I wasn't the only one confused by this, I was about to make the same comment!
