• if there is a relationship between the two variables and the direction of that a relationship is positive or negative 
• a positive correlation is when the correlation coefficient is 
• assumptions and cautions 
• the correlation coefficient is only an index of the linear relation between two variables 
• correlation does not imply causality 
• correlation does not queal causation 
• excel correlations 
• correlations are an efficient way to asses the relationship among many numerical variables at once
