1. The linear correlation coefficient r measures of the linear relationship between two variables. (a) Distance (b) size (c) strength (d) direction 2. 10 pairs of sample data were obtained from a study which looked at household income and the number of people in the household who smoked (cigarettes). The value of the linear correlation coefficient r was computed and a result of - 0.989 was obtained. All of the following (below) are conclusions that can be drawn from the result EXCEPT: (a) There is a significant relationship between income and smoking. (b) The relationship between income and smoking is negative. (c) Households with higher incomes tend to have more smokers. (d) Households with higher incomes tend to have fewer smokers. 3. The value of r is always between _ (a) 0 and 1 (b) -1 and +1 (c) -0 and +1 (d) 0 and 5

A linear relationship exists between 2 quantitative variables. The correlation coefficient is -0.14. Which of the following is true? A transformation should be done to try to make the correlation coefficient positive and closer to 1. There is no evidence to indicate a relationship exists between the two variables because of the negative correlation coefficient. This indicates a strong relationship between the two variables. This indicates a weak relationship between the two variables. This is impossible as correlation coefficients can’t...
