Question

Which value of r indicates a stronger correlation than 0.25?

Multiple Choice

• -0.30

• -0.30, -0.50, 0.30

• 0.30

• -0.50

Answer 1

given data,
value of r indicates a stronger correlation than 0.25
value of correlation is =0.25
coeffcient of determination = r^2 = 0.0625
properties of correlation
1. If r = 1 Correlation is called Perfect Positive Corrlelation
2. If r = -1 Correlation is called Perfect Negative Correlation
3. If r = 0 Correlation is called Zero Correlation
& with above we conclude that correlation ( r ) is = 0.25> 0 ,positive correlation              
0.30 is the stronger correlation than 0.25 because positive correlation and remaining options are -0.30 and -0.50 both are strong negative correlation.
so that,
0.30 is the greater than 0.25 and remaining are less values than 0.25
Answer:
0.30 is the stronger correlation than 0.25
