Spearman r is a non-parametric test that measures the strength of the relationship between two variables, whereas Pearson r is a parametric test that measures the linear relationship between two continuous variables. If a Spearman r were used on data requiring a Pearson r, the correlation coefficient obtained may not accurately reflect the true linear relationship between the two variables. In order to obtain significance, a larger sample would be required as Pearson r is more sensitive to sample size than Spearman r.
