• Scatter plots are bivariate; they visually display two scores for each person.
  
  
• Correlations describe the linear association between two variables.
  
  
• The degree of scatter in a scatter plot expresses the strength of the association between two variables; the more the data points are scattered around the line, the weaker the association.
  
  
• We have three types of correlations: (1) positive correlation, (2) negative correlation, and (3) zero correlation.
