Spearman's Rho stats test

• What type of test is Spearman's Rho?

  Correlation
• What level of data is required for Spearman's Rho?

  Ordinal data
• What are the 7 steps for Spearman's Rho?

  1. Plot the data in the table
  2. rank all the variables
  3. Calculate the difference between the ranks of variables 1 and 2 (take variable 2 rank from variable 1 rank)
  4. Calculate the difference between the ranks squared
  5. Calculate the sum of the differences between the ranks squared
  6. Use the formula to calculate the observed value
  7. Use the critical value table to find the critical value
• What is the formula for Spearman's Rho?

  $r=$$\frac{6\sum_{ }^{ }d^2}{n\left(n^2-1\right)}$
• What does N stand for in Spearman's Rho?

  Number of pairs of scores
• When is Spearman's Rho significant?

  When the observed value is greater or equal to the critical value
