# stuck on outlier question S1

#1
Hey guys, below is the question:

Male and female turtles were weighed in grams. For males, the lower quartile was 400 g and the upper quartile was 580 g. For females, the lower quartile was 260 g and the upper quartile was 340 g.
An outlier is an observation that falls either 1 × (interquartile range) above the upper quartile or 1 × (interquartile range) below the lower quartile.
a Which of these male turtle weights would be outliers?
400 g 260 550g 640 g
b Which of these female turtle weights would be outliers?

170 g 300 g 340 g 440 g
c What is the largest size a male turtle can be without being an outlier

I understand how to do a. But with b I keep getting it wrong, this is my workings:

b) UQ - 340+(1.5 x 80) = 460 -----
LQ -260 - (1.5 x 80)= 140-------Therefore there are no outliers?!

Also, for c should it not be 580 + (1.5x180) = 850?

So confused, could someone please kindly tell me where I am going wrong!

What formula do they tell you to use in the question?

??? They don't tell you to use anything, apart from the UQ +(1.5 x IQR) and LQ -(1.5 x IQR) which I've used, but somehow it's the wrong answer.

Assuming you've copied the question out correctly, go back and read the formulae one more time.

Your workings seem to be correct for both parts.

Are you serious right now? Look at when the question was asked.
That person would have finished his/her A-levels by now

Or they could have died in a gigantic train-crash.

At least we stopped them turning in their grave...

I don't care, the question doesn't make sense though

No no. That wouldn't happen.
But seriously, I would feel really shocked if something like that happens. If a person to whom I've talked, dies, I would really feel like something. Mixed emotions with shock.

Don't take my reply (my first one) as an offense. I was just joking.
I did that question last week and it was very easy. You just have to use the formula given in the book. Simple.

Yup, trudat. I've lost 2 close friends to suicide. I swear it will never get easier.

Shock is one of the feelings you get, but it periodically trades places with almost every other emotion under the sun tbh. It's a bad rollercoaster...
