Spearman's correlation coefficient, (ρ, also signified by r s) measures the strength and direction of association between two ranked variables. Various analytical and interpretational misconceptions are reviewed, beginning with the egregious assumption that correlational statistics may be useful in inferring causality. Uses of Correlation Analysis It is used in deriving the degree and direction of relationship within the variables. When working with continuous variables, the correlation coefficient to use is Pearson's r. A correlation between variables, however, does not automatically mean that the change in one variable is the cause of the change in the values of the other variable. According to Madiha Shah (2014), the online information system usage in educational management Suggested Grade Level: When two variables have a positive . For example, in the stock market, if we want to measure how two stocks are related to each other, Pearson r correlation is used to measure the degree of relationship between the two. However, misuse of correlation is so common among researchers that some statisticians have wished that the method had never been devised at all. I used a simple statistics program to generate random data for 10 variables with 20 cases (i.e., persons) for each variable. Possible correlations range from +1 to -1. Beyond such hyperbole, the implications of the Internet for education and learning can be understood in at least four distinct ways. Schools with high test scores also have high graduation rates.
