This example shows how very different a median vs. an average really is...
If we could get the CFF to admit the average it would be much higher because all the adult onset diagnosis' would weigh a lot heavier.
A median is a middle number. So when they say the median is 36.8 they are referrring to someone's specific death at the age of 36 years and 9.6 months as reported in cf registries. Also remember not everyone is followed at accredited cf centers. Those patients aren't accounted for.
Median:
5 patients died at these ages. The median is 36.
1, 2, 36, 56, 65
Average:
5 patients died at these ages. The average is 36.6
5, 21, 32, 50, 75
We need to demand for accurate data. The one that really ruffles my feathers is that the CFF still reports 30,000 people with cf. They have said this number as long as I remember. Maybe even back when I was born in 1978. When is someone going to call them out on it? The number has to flucuate.
I have it set in my Outlook to email them questioning this every 6 months. I've been doing it for a few years now and no one ever responds....hmmm....sort of makes you wonder doesn't it.
Long story short - don't rely on numbers anyone tells you about anything. Really no one has a clue...until there's a cure, there's going to be a lot of misinformation.
