Two variables negatively correlated example
WebCorrelation is the relationship between the two variables in a bivariate data set. Such relationship can have certain tendencias that would allow us to see if the variables have an interdependency or if they are affected by the other in any way. Correlation can be positive, negative, zero (or no correlation) and curvilinear. WebConsider your work environment, domain of interest, or everyday life, and provide one example of two variables that are positively correlated and one example of two variables that are negatively correlated. Explain why your correlation examples are positive and negative. Review a peer example, and discuss areas of difference.
