1. Correlation basics Which of the following statements about correlation are true? Check all that apply. O If the correlation between two variables is close to 1, there is a positive linear relationship between the two variables. O The sign of the correlation indicates the strength or consistency of the linear relationship between two variables. O If the correlation between two variables is 0, there is no clear linear relationship between the two variables. O The sign of the correlation indicates the direction of the relationship between two variables. O Correlation measures and describes the behavior of a single variable. O The correlation is scaleless; that is, it doesn't change when the measurement units are changed for either or both of the variables. O The correlation indicates the strength and the direction of the linear relationship between two variables.
