Question

Answer the following questions regarding the strength of correlation true or false?

1. R = - 0.55 is stronger correlation than R = 0.50 ?

2. R = 0 is stronger correlation than R = - 0.10?

3. R = 0.67 is stronger correlation than R = - 0.67

4. R = - 0.7 is stronger correlation than R = - 0.56

5. R = 0.86 is stronger correlation than R = 0.75

Answer 1

1) False

2) False (R = 0 MEANS NO CORRELATION)

3) True

4) False

5) True

Explantion:

• Exactly r = –1. A perfect downhill (negative) linear relationship
• r = –0.70. A strong downhill (negative) linear relationship
• r = –0.50. A moderate downhill (negative) relationship
• r = –0.30. A weak downhill (negative) linear relationship
• r = 0. No linear relationship
• r = +0.30. A weak uphill (positive) linear relationship
• r = +0.50. A moderate uphill (positive) relationship
• r = +0.70. A strong uphill (positive) linear relationship
• r = Exactly +1. A perfect uphill (positive) linear relationship
