Question
Correlation between to variables, A and B is .09. Then which of the following statements are true (Note: There may be more than one. Answer carefully)
A. A and B are positively Correlated
B. If A goes up, B also tends to go up
C. If A goes down, B also tends to go down
D. If A goes up, B tends to go down
E. If A goes down, B tends to go up
F. A causes B to increase
G. B causes A to increase
H. A and B are negatively correlated
Which of the statments are true:
1. Only A is true
2. A, B and C are true
3. B and C are true
4. A,B,C,F, and G are true
**** I think the answer is 2. A,B, and C are true
Please explain how you got the answer
Explanation / Answer
Solution: 2. A, B and C are true
Correlation between to variables, A and B is .09.
Whenever the value of correlation betweeen two variables is positive then we say that A and B are positively correlated.
Positive correlation is a relationship between two variables in which both variables move in tandem. A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.
Therfore A,B and C are true.
Negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa.
D, E, H are False beacuse the variables are positively correlated They wil be true if variables are negatively vorrelated.
Correlation does not imply causation means that a correlation between two variables does not imply that one causes the other.
Therefore F and G are False.
