Question

Select Strong association, Weak association, or Moderate association to correctly classify each correlation coefficient.



Correlation coefficient Strong association Weak association Moderate association
0.4
−0.96
−0.1
−0.54

Answer 1

0.4- Moderate Association
-0.96-Strong Association
-0.1-Weak Association
-0.54-Moderate Association
Any value between 0.3 and 0.7(or -0.3 and -0.7, respectively) has a moderate association. Higher than 0.7 is strong and lower than 0.3 is weak. 
Hope that helped!

Answer 2

Answer with explanation:

→The value of Correlation Coefficient(r) lies between :

-1 ≤ Correlation Coefficient(r) ≤ 1

⇒If, r=0,then there is no Correlation between two variables.If value of r,is closer to 0, and greater than 0,it means ,weak positive correlation,and if value of r, closer to zero,and is less than 0, it means weak negative correlation.

⇒If r, is closer to , -1, then it means ,strong negative association between two variables,and closer to +1, then strong positive association between two variables.

1. r= 0.4, ⇒Moderate Positive association

2. r= -0.96⇒Strong Negative association

3. r= - 0.1⇒Weak association

4. r = -0.54⇒Moderate Negative association
