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