Heres the thing you gotta understand about statistics. 

“Increases your chances by 80%” does not mean “there is now an 80% chance”. 

If your chances were previously 10%, your chances are now 18%, not 90%. 

if your chances were roughly 1%, they’re now just slightly less than 2%. 

thats how that works. 

Wow I don’t understand math at all

‘if you have a baby after 35, the chance of deformities goes up by 100%’ is a line I hear alot.

It goes up from .5% to 1%

To simplify: It’s the percent amount of the current factor.

In the starting example: 10% is the factor. 80% of 10 is 8, and then add together (increase by that): 10 + 8 = 18. Thus an 80% increase of 10% is 18%.

Similarly: 1% is the factor, it’s really the same as 10, just the decimal stepped over (10.0%, 1.00% // I know that isn’t really how numbers work, I’m just doing this for the visual). And thus, 80% of 1% then adding it on would be basically 1.8%

And finally, .5%. 100% of .5 is just that, ‘point 5′, or a half a percent. Two halves make a whole, and thus a single percent or ‘1%’.

Pretty easy to be honest… Though, it’s easy to get caught up in the statement and forget that, sometimes even when you know better.

I think my brain just stopped working

100% is just another way of saying twice more likely. So 100% more basically means multiply the number you do have by 2.

It goes up by that percentage of the previous number.

For example, let’s say your chance was 10%. It just went up by 10%.

10 is a.. factor? Idk it’s related to 100. So 10% of 10 is 1 (10% of 100 is 10, but I at least think that’s obvious since % is based on 100)

So your chance is now 10% + 1% which is 11%. Or 10% + (10% of 10%), which is 11.

finding out people dont usually add numbers by first adding something to make a ten (for example 7+6= 7 plus 3 is 10 plus another 3 is 13) & that its actually an adhd thing is the WILDEST shit literally ive lived like 10 years (or however old i was when i learned to add and stuff) thinking thats how everyone does it. what the fuck

WHAT

What? How the fuck do other people count? 

I think people just know smaller numbers like that because however their brain does it just happens quickly.

With bigger numbers I don’t know how else you’d do it besides going to a factor of ten and then adding the extra
