Spearman's Rank Correlation Coefficient Review Spearman's rank correlation coefficient is a mathematic and statistics tool used to measure correlation or in other words, there is a number that reveals how closely related, two sets of different data can be associated and how closely related they are. This can only be used with information that can be put in rank order from highest to lowest. The Spearman's rank correlation coefficient is also used to determine whether the two variables are associated or related in any monotonic way, in which a variable will increase and the other variable will also increase or it will decrease. As a result of this, the measurement will be converted to ranks therefore researchers will use the Spearman's rank …show more content…

As part of this research Messina et al. used the Spearman rank correlation coefficient to help determine any relationship between the mean score of patient satisfaction (independent variable) and the admissions volume (dependent variable).The patients were given surveys/questionnaires to be filled out which they graded on a ranking scale of their own satisfaction on the hospital type they received their treatment. The results of this research using the Spearman rank correlation coefficient, has shown that there is a significant but negative correlation between the variables in the combined sample between admissions and patient satisfaction. The research performed by Messina et al. (2009), definitely answers the research question if there is any relationship between patient satisfaction and inpatient admissions across teaching and nonteaching hospitals. When one looks at the Spearman's rank correlation coefficient results by itself you will see that there is statistically a significant and positive correlation between the patient satisfaction and the admission volumes in teaching hospitals (Messina et al.,
