Question

71. Re-write the following r values from the Pearson Correlation in order from weakest to strongest. (5 marks)

-0.86 -0.43 0.01 0.095   0.68

________ ________ ________ _______ ________

Weakest    Strongest

Answer 1

Q.71) Note : The Pearson correlation is lies between -1 to 1.

The correlation is gets stronger as it goes close to -1 or 1 and as it goes to zero it becomes weaker.

Here, r = -0.86 is stronger than others and r = 0.01 is weaker than others.

=> r = 0.01 < r = 0.095 < r = -0.43 < r = 0.68 < r = -0.86

Therefore, the given correlations in order from weakest to strongest as follows :

0.01, 0.095, -0.43, 0.68, -0.86
