Which of the following statements about the Spearman rank-correlation coefficient is true? A) It is equal to the Pearson correlation coefficient of the ranks of the data. B) The population Spearman correlation coefficient is labeled $\rho$_s. C) Values near +1 point to an uphill relationship between the two variables. D) All of these choices are true.

A) This statement is true. The Spearman rank-correlation coefficient is calculated by first ranking the data and then calculating the Pearson correlation coefficient on the ranks. B) This statement is false. There is no such label as "F1F1F1S1F1F1F10_s" for the population Spearman correlation coefficient. C) This statement is also true. The Spearman rank-correlation coefficient ranges from -1 to +1, where values near +1 indicate a strong positive correlation or an uphill relationship between the two variables. Therefore, the best choice is D.
