Spearman's rank

• How do you identify the null hypothesis for SR?

  "There is no significant correlation between these two sets of continuous data"
• How do you calculate Spearman's Rank?

  $rs=$$1-\left(\frac{6\ \times D^2}{n^3-n}\right)$
• How do you conclude Spearman's rank?

  Our calculated value of Spearman's Rank correlation coefficient is greater/less than the critical value for p=0.05.

  There is less/more than 5% probability that the (positive/negative) correlation between {} and {} is due to chance.

  We accept/reject our null hypothesis.
• What does D stand for in Spearman's rank?

  Difference between the rank of paired measurements.
• What does the n stand for in Spearman's rank?

  Number of paired measurements.
