4] Now run a t-test to test the significance of your Rs value. Remember to use the absolute value of your correlation coefficient! This will tell us if the Spearman Correlation Coefficient is greater or less than zero. What is your calculated t-value (associated with the Spearman Correlation Coefficient)? What does this tell you? Is this going to be a 1 or 2-tailed test? Explain.

5] What is the t-critical value for this test at both the 5% and 1% significance levels? After comparing your calculated t-value to your critical values, what do you conclude? Of the two t-critical values, in which value would you have the greatest confidence?

6] What did you conclude as a result of this test? Include the following information:a] the magnitude of that relationship [weak, moderate, strong]b] the direction of that relationship [positive or negative]

7] Which of the following is the correct range for ANY calculated Spearman Correlation Coefficient?

a] any number up to infinity [either a positive or negative value]

b] 0-1 [only a positive value]

c] 0-1 [only a negative value]

d] 0 to 1 [either a positive or negative value]

Part 2 - Week 11: Spearman Correlation The following data are made up, but were based on a study relating average spring snowmelt date and wildfire frequency. Note that the general pattern is greater wildfires for earlier snowmelt dates.
