Write a paperwords regarding the use of the Spearman rank correlation coefficient by Messina et al. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful completion. Complete the "Yeung Analysis Worksheet. First, a perfect Spearman correlation results when X and Y are related by any monotonic function.

The Spearman correlation coefficient is often described as being "nonparametric". Choose one of the other tools studied so far in this course and explain why it would not provide relevant findings.

This can have two meanings. In continuous distributions, the grade of an observation is, by convention, always one half less than the rank, and hence the grade and rank correlations are the same in this case. While APA format is not required for the body of this assignment, solid academic writing is expected, and documentation of sources should be presented using APA formatting guidelines, which can be found in the APA Style Guide, located in the Student Success Center.

Example[ edit ] In this example, the raw data in the table below is used to calculate the correlation between the IQ of a person with the number of hours spent in front of TV per week.

Please refer to the directions in the Student Success Center. If Y tends to decrease when X increases, the Spearman correlation coefficient is negative.

A Spearman correlation of zero indicates that there is no tendency for Y to either increase or decrease when X increases. The Spearman correlation increases in magnitude as X and Y become closer to being perfect monotone functions of each other.

A perfect monotone decreasing relationship implies that these differences always have opposite signs. Contrast this with the Pearson correlation, which only gives a perfect value when X and Y are related by a linear function.

Correlation and dependence There are several other numerical measures that quantify the extent of statistical dependence between pairs of observations.

You are required to submit this assignment to Turnitin. An abstract is not required. A negative Spearman correlation coefficient corresponds to a decreasing monotonic trend between X and Y.According to the Pearson correlation coefficient, the closer the coefficient (R2) is to one, the more “perfect” the correlation between the items being.
