A stats question

Got this stats question that I am kind of like what the hell 🙂

Does an increase in the crime rate from 4% to 6% represent an increase of 50%?

I think it does since 1/2 of 4% is 2% which added to 4% equals 6%. Any suggestions? thanks!

As far as I know, that's how it works, your logic is correct.

Now in my defense, I've never taken a stats course. I understand the simple stuff, so I think I'm right, but NeverDone, I'd wait for another person to agree. 👍

ya, if you have a 100% increase in apples, and you had one apple, you'd then have two apples. An additional 50% increase would but you up to 3 apples. Add another 300% increase, then you're sitting on 9 apples. Increase that times 8 for an 800% increase, then you have 72 apples. Lose 50%, then 36 apples.

I find that if i make all stats fruit-based, it just clicks. Fruit helps in chemistry too. Full of vitamins and stuff also.

technically your logic is correct, but when looking at something like crime - keep the population size in mind. if outta 100 people, 4 people committed a crime last year, and 6 this year, its not a significant increase as 50% would indicate.

wouldn't it be great if sdn had a subforum for questions like this?

(i'm not kidding... i think it would be a great addition to the site)

LOL thanks you guys, I will try to keep it to fruit, especially since I like it 🙂 The population stays the same so is the answer still correct? Thanks for all your help. Yeah I think there should be a sub section for homework questions,,think of all the help we could get!

It's a fifty percent increase in crime for that hundred people. But if on average 4/100 people commited crimes and it raised to 6/100, that's a 50% increase in crime. 100% + 50% more.

I think you're saying that if you take one-hundred people out of the population and...wait...i don't really know what you're saying.

Oh wait, I get it. Sounds like a huge increase in crime. You have to look at the starting value in comparison. Sorry, brain turned off. Ya, stats like that can sound scary. Actual figures are best.
