I am sorry you are wrong.

Lol we don't understand? You surely don't know your statistics, why the **** would you rank inconsistently?

dumbest thing i've ever heard in my life. It does matter if it is negative or positive, hence negative or positive correlation, you clapped child, go do your SATS. I am asian we know everything.
Well, obviously, if you have the ranks running in the opposite direction, the correlation will flip from positive to negative or vice versa. Therefore, the relationship between the two variables is still the same.

Draw the scatter graph it portrays negative correlation, for the data in the question.

But Spearman's Rank doesn't measure correlation in that sense, it measures correlation between your ranks. So, if number 1 was the best position, then you would get "the faster the serve, the better the world position'. Which is a positive correlation between your ranks.

I am flabbergasted by your idiocy, please so you are trying to tell my comrades and other members on the student room that there is not difference between a positive and negative correlation. I believe you should pick up a revision guide and use it. You do not know statistics if your are correct and i am certain that you are not i will hand my cock to you 'exhalted member'.

For 3d) where it asked what is wrong with this question with options yes, no and I don't know I wrote there is no option for 'maybe' and it is an open question would I get the mark? Please reply!

Mate if you flip your ranks the other way round, you are also going to flip the correlation ????? Please, if you don't understand, trust me.

spearmans rank measures the strength of a datas correlation it also measures the whether it is positive or negative or positive, you have to measure it consitently otherwise its wrong. unless you will start to tell me that a positive correlation on a graph is negative.

Yes, ultimately it does. There is a positive correlation between "the speed of serve, and the lower in world ranking". That is what a positive answer tells us, from ranking 1st place 1.

However if you rank 1st place 10th, then you will get a negative answer telling us that:

There is a negative correlation between "the speed of the serve, and the higher the rank".

This clearly, demonstrates how the two answer mean the same thing, it is just whether you determine 1st position to have a higher rank that 10th position or not. In my opinion, it should do so my results will be in simpler language:

"The higher the speed of serve, the better the world ranking"

OR your result in clearer words would be:

"The higher the serve, the lower the world ranking"
15. Re: Edexcel GCSE Statistics Higher Tier Answers June 2012
I will enlighten you by providing you with this scatter graph, which shows that the correlation is negative.

Speed was ranked as being better when it is higher hence, around 120mph had rank 1. I deemed the lower the position, the better the rank. So 1st place would be Rank 1. Do you not understand that Spearman's Rank calculates the correlation between our ranks and not the actual values?

No sorry you are incorrect
Noooooooooooo, that's cringeful, get that off. That shows negative correlation as well That is exactly what Spearman's Rank told us it would show with those scales "the lower the position, the higher the speed". However, it would tell us that whether our value was negative or positive.
