i have been doing the questions for the event.

one answer says 25% of youth are getting treatment.

one answer says 78% of young people who need treatment are not getting it.

are youth and young people not the same thing? is one set minors and the other set college and career age? then the problem is english?

25% would be 22% of those who need treatment if they are the same set. making it 112%.

another answer is 75% with illness get it before age 18.

does that mean that at age 18, 78% of the 25% stop going to treatment? when it is their choice?

at any rate, the emergent structure is a train wreck, and only going to get worse if we keep feeding the wrong wolf.

The following calculations use the numbers you have provided.

Start with 100% of the youth population.

Split this into two sets: Those who are ill (25%), and those who are not (75%).

Now take the "ill" set. Of these, 22% are getting treatment, and 78% are not.

Therefore, 22% of 25% of 100% = 5.5% of the youth population are receiving treatment.

78% of 25% of 100% = 19.5% of the youth population are not receiving treatment, but may require it.

The remaining 75%, as mentioned, are not ill, therefore do not require treatment.

---

I don't know where you got that 112% from. If you're trying to add 25% to 78%, then you'd come to 102%.

---

Here's another example.

Start with 100% of the whole population who are ill.

Split this into two sets: Those who started being ill before the age of 18 (75%), and those who started being ill after the age of 18 (25%).

This is all we can say based on the numbers given. There is no link between these numbers and people stopping their treatment at the age of 18. In fact, there's nothing here to say anybody's getting any treatment at all. It simply states the point in life when these people become ill.

I hope this clears up the maths for you. Based on the information you've given, I can't see anything wrong with it.

thanks for answering. weird the answers say the exact opposite as i read it.

Zoed: What percentage of young people are receiving treatment for mental health conditions? 25%. this states are receiving treatment, not who needs treatment.

your answer was: 5.5% of the youth population are receiving treatment.

the second answer:

Kal: What percentage of youth go without treatment for poor mental health? 78% this states who needs it, not who is receiving it. your answer was 19.5% of the youth population are not receiving treatment, but may require it.

so if 78% not getting treatment, then 22% are getting treatment, the 22% and 25% would represent the same set.

see the problem with the math?

the final part i did in case it is 2 separate sets we are talking about:

the first set {youth} at 25% getting treatment.

the second set {young people} not getting treatment.

if 25% are getting treatment as {youth} but 78% not getting treatment as {young people} who need it. therefore 78% of the 25%. the difference between under age 18 and over age 18.

i got 112% by simply taking the difference between 25% and 22% being 3% and multiplied by 4. might not be the right way to do it, but it was a guesstimate.

i think the math in the first part remains the same. if they are one set.

in the second part however if they are 2 sets, and the youth and the young people are flip flopped, it would seem to indicate that 25% of college and career age who need treatment get it, however 78% of that 25% don't get treatment as minors.

that seems even more odd to me. self diagnosis vs. the diagnosis of school and parents.

I was just reviewing the questions, and the whole thing is completely useless. Other than to point out there is a problem out there, and that these groups are trying to help. I guess that is enough.
