Which of the following correlation coefficients indicates sufficient evidence of linear correlation? Select one: a. r = 0.9 b. r = 0 c. r = 0.09 d. r = 9
Homework Answers
Answer: Option a) r = 0.9
The correlation coefficient r = 0.9 indicates that there is very straong linear positive ralationship between the two variables.
Where as r = 0 shows there is no linear relationship exist between two variables.
r = 0.09 shows that there is very low linear relationship between the two variables.
and the correlation coefficent r =9 is not correct because the range of correlation coefficient is -1 to 1.
