#### Spearman rho vs pearson realize  What are some reasons to use Pearson correlation instead of Spearman or Kendall? Feedback post: Moderator review and reinstatement processes. Add to. The assumptions of the Spearman correlation are that data must be at least ordinal and the scores on one variable must be monotonically related to the other variable. But I've seen that the variable has been correlated with other variables using Pearson's r. Leave this field empty.

The following formula is used to calculate the Pearson r correlation:. Spearman correlation is often used to evaluate relationships involving ordinal variables. The chart shows an undisputable positive monotonous relation between size and revenue: larger companies tend to make more revenue than smaller companies.
