Question 157

A glaciologist is investigating the linear relationship between the temperature of the ice, TTT, and the concentration of a trapped gas, GGG. Four different models suggest the following potential values for the product moment correlation coefficient, rrr, for their dataset:

  • r=sin⁡(4)r = \sin(4)r=sin(4)
  • r=ln⁡(0.5)r = \ln(0.5)r=ln(0.5)
  • r=π3r = \frac{\pi}{3}r=3π​
  • r=2−2r = \sqrt{2} - 2r=2​−2

Which of the following is not a possible value for rrr?
