This is Pearson Correlation, not Spearman. How did it go?

@statslectures I meant that the X & Y scores n the tables that you rank their values are not the ones plotted in the scatter diagram, right? - i'm just asking

Does the variables have to be of the same type or can one be continuous and one ordinal for Spearman to be accurate?

Um? How did it go? The formula used is for Pearson Correlation and not Spearman Correlation.
@fkanellis
@fkanellis 12 лет назад
The scatter plot you present is not related to the sample data set you base your calculations on, correct?

And what if i have the same rank twice in Y? 6,5,1,2,3,4,4?
@samikshapadole5614
@samikshapadole5614 4 года назад
Yes I've the same question
@hubertvictorino5394
@hubertvictorino5394 4 года назад
It would be 7,6,1,2,3,4,4. Because the 2nd 4 would've taken the place of 5

@daday9760 3 года назад
Your formula is not for Spearman correlation. This is for Pearson Correlation.

The formula.... you got it wrong !! It is Pearson Formula, not Spearman. The results is correct but the formula is wrong, also Spearman Correlation use d and d square, not XY.
@daday9760
@daday9760 3 года назад
True. This is Pearson, not Spearman. I'm about to get confused. Good thing I read my modules first.

Actually, if there are no ties and the ranks are used in the Pearson formula calculation instead of the raw data, the result is algebraically equivalent to Spearman’s rank formula.
@michelerich1590
@michelerich1590 10 лет назад
but why did you use 1-6?
@dianzhang6035
@dianzhang6035 10 лет назад
they are called "ranking", basically, just sort the value and the 1-6 is the order. E.g if the value of x is 0.1, 0.3, 0.2 then your order will be 1,3,2

Dian Zhang Oh, ok! Thanks. I get it :)
@terefeadugna9797
@terefeadugna9797 8 лет назад
+Dian Zhang,Hey Sir, is there a way in which we can link the function to new data and find automatically the solution? i.e ranking helps to know the order of original number and in case we have a lot of data replacing corresponding data manually is not handy
@lijitha9991
@lijitha9991 4 года назад
@@terefeadugna9797 In continuation to the question,In spearman does it mean that X and Y just needs to be ranked for the given data,for eg if X is 22,32,42,11 and after ranking X would be 11,22,32,42 ??
