Spearman coefficient review essay

A negative Spearman correlation coefficient corresponds to a decreasing monotonic trend between X and Y. This can have two meanings. 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.

This assignment uses a rubric. If Y tends to increase when X increases, the Spearman correlation coefficient is positive. Please refer to the directions in the Student Success Center. A perfect monotone decreasing relationship implies that these differences always have opposite signs.

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. Hire your writer directly, without overpaying for agencies and affiliates!

If Y tends to decrease when X increases, the Spearman correlation coefficient is negative. Thus this corresponds to one possible treatment of tied ranks. Correlation and dependence There are several other numerical measures that quantify the extent of statistical dependence between pairs of observations.

The Spearman correlation coefficient is often described as being "nonparametric". The sign of the Spearman correlation indicates the direction of association between X the independent variable and Y the dependent variable. The Spearman correlation increases in magnitude as X and Y become closer to being perfect monotone functions of each other.
