Rosala, did you just say that

$$\frac{2}{5}\times 5=5 ????$$ 

I don't think that is what you meant but that is what it looks like. 

775-x       metres

Hi Happy :)

Just enter it on the home page calc. :)

I don't think you need to change anything!

the * means nothing

(+5)^2 = 5^2 = 5*5=25

Hang on Rosala, I don't think that works.

do you want to take a look at that calculation again?

logπ(5)+logπ(11)=logπ(55)

52,44,32,29,28,28,23,20,18,17,16,15,13,11,9,8,8,5,4,4,2,2,0

there appears to be 23 scores.

the middle position is (23+1)/2 = 12,   15 is in the 12th position so 15 is the median.

Now there are 11 scores on either side of the median.

the middle position of these is (11+1)/2 = 6  the 6th score from either end  is 28 and 12

12 is quartile one or the lower quartile and

28 is quartile 3 or the upper quartile.

Now come on ultmage, you can do some of that yourself.

You can see the min and max as clearly as I can.  And the median is just the middle score.
