pls the second formula containing the di does it only apply wen there are no data ties, and also since u said the spearman is the same as the pearson except for spearman we use the rank of the data does it mean wen calculating for the spearman u can either use the pearson formula but just that ur x and y variables will be ur rank and wen there are no ties u go ahead and use the second formula, and also can u also do a video on examples using pearson and spearman without the statistics calculator i mean manually pls🙏🙏🙏🙏🙏
